HIP --- | Note --- |
---|---|

171 | Poor HIP sol. |

1242 | Too poor astrometric orbit (Ianna et al., 1988AJ.....95.1226I) and too |

1242 | few resolved observations (cf. Heintz, 1990Obs...110..131H) to give |

1242 | definite orbit. Present solution at least preferable to `X' HIP-sol. |

1674 | Uncertain `visual' edge-on orbit. |

2237 | High-eccentricity, half-period solution fits equally well but gives too |

2237 | high mass-sum (with no third component allowed by q). |

2552 | Aa-B triple sol (double (Aa)-B in HIP). Orbit mostly dependent on |

2552 | Hershey (1973AJ.....78..935H) pc observations, more IR speckle needed. |

2762 | Visual primary is 2.1d SB 1 (#27 in Batten et al., 1989PDAO...17....1B). |

2762 | Speckle orbit in Hartkopf et al. (1989AJ.....98.1014H). |

6564 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

7372 | AB-C triple+var sol (AB in HIP). B is 0.47d ecl bin (BB Scl). |

7580 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

7918 | Improved pc ({Delta}m>6) orbit combining pg (Lippincott et al. 1983) and |

7918 | Hipparcos obs. Scaling by the speckle IR (Henry et al., |

7918 | 1992AJ....103.1369H) gives orbit size and mass-ratio. |

10535 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

10542 | Orbit poorly covered, period rather indeterminate. |

11569 | Aa-B-C quadruple solution (AB in HIP). High mass-sum, strangely |

11569 | well-behaved speckle obs at {Delta}m=4?? |

12390 | Speckle orbit in Hartkopf et al. (1989AJ.....98.1014H). |

12717 | More speckle obs needed to define orbit. |

14879 | Another century needed for apastron coverage. |

14913 | AB-C triple solution |

15799 | Possible orbit from two widely spaced vis obs + Hipparcos data. |

16602 | Cf orbit in McAlister et al. (1992AJ....104.1961M). |

19719 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

19758 | Half-period solution equally good, but gives large mass-sum. More |

19758 | speckle-obs needed (the only existing one erroneous?). |

20087 | Hyad(vB 24), cf. Torres et al. (1997ApJ...474..256T). |

20215 | Hyad(vB 29). |

20347 | The 4d SB 1 (Worley & Heintz, 1983PUSNO..24g...1W) probably spurious. |

20661 | Hyad(vB 57), assumed period from Torres et al. (1997ApJ...479..268). |

20686 | Hyad(vB 58). |

20885 | Hyad(vB 71), G7. III spectrum, assumed period and mass-ratio from |

20885 | Torres et al. (1997ApJ...485..167T). |

20916 | Hyad(VB 75). |

21280 | Hyad(vB 96). High mass-sum, illustrative solution only, |

21280 | speckle/spectroscopic orbit needed, cf. Griffin et al. |

21280 | (1988AJ.....96..172G). |

21594 | K1III spectrum, speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

22505 | Hyad(vB 120). Preliminary circular orbit, speckle/spectroscopic orbit |

22505 | needed, cf. Griffin et al. (1988AJ.....96..172G). |

22550 | Hyad(vB 122). Mass-sum calls for sp subsystem, but RV-ampl <1km/s |

22550 | according to Griffin et al. (1988AJ.....96..172G). |

22607 | Hyad(vB 124), primary is 143d sp bin (Griffin et al., |

22607 | 1985AJ.....90..609G). |

23395 | Visual separations systematically too small. |

23452 | Good period, indeterminate a/e/i, more obs needed!. |

23835 | Visual and speckle observations at 0.1arcsec separation ruled out as |

23835 | spurious by constant RV (Duquennoy and Mayor, 1991A&A...248..485D). |

28442 | AB-C triple solution (HIP data unuseable!). Speckle obs needed to |

28442 | strengthen orbit. |

28614 | Pr 4.4 SB 1, sec 4.8d SB 2 (Fekel, 1980PASP...92..785F), reasonable |

28614 | mass-sum. |

28734 | Pr 9.6d SB1 (#377 in Batten et al., 1989PDAO...17....1B), sec K1III |

28734 | (Strassmeier & Fekel, 1990A&A...230..389S), mass-sum close to expected. |

29234 | High mass-sum, speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

30920 | Good resolved solution with the aid of scattered visual+(IR)speckle |

30920 | observations. Mass-ratio calculated from pc orbit size (Probst, |

30920 | 1977AJ.....82..656P). |

30953 | Difficult a/e/i-correlation, more obs needed. |

30953 | AB-CD quadruple solution. |

33142 | Fixed e,i,{omega},{Omega} from Heintz (1990A&AS...82...65H). Needs |

33142 | combined astrometric/visual/Hipparcos solution. |

33449 | G5III-IV spectrum. Period poorly determined from old vis obs. |

33451 | A few more speckle-obs will strengthen orbit considerably. |

35296 | The 94-yr orbit by Heintz (1995ApJS...99..693H) plus the HIP parallax |

35296 | gives impossibly small mass-sum. Probably both a and P are much larger |

35296 | (no orbit for another century), but motion should be followed. |

36238 | Good fit to speckle/Hip, but implausibly large masses even for a |

36238 | multiple system. Speckle/spectr sol pending (Hartkopf et al., 1997, |

36238 | CHARA Contr. No. 4, (on-line electronic version)). HIP sol spurious. |

38052 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

38382 | Speckle orbit in Hartkopf et al. (1989AJ.....98.1014H). |

38474 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

40167 | 2-orbit AB-Cc quadruple sol (AB-C in HIP). |

40239 | Present {pi}-value adopted instead of poor HIP-value. |

42075 | Giant primary according to isochrone fit. |

42748 | Period around 100 y, rapid motion at present, more obs needed. |

43109 | AB-C triple sol ((AB)-C in HIP). G0III-IV spectr, speckle orb in |

43109 | Hartkopf et al. (1996AJ....111..370H) |

43671 | Low incl fixed at 15{deg},({Omega}=0). High mass-sum and q=1.5(0.3) |

43671 | corroborates secondary 9.1d SB2 (Worley & Heintz, 1983PUSNO..24g...1W). |

44248 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

45170 | Reversed {Delta}m and slightly larger parallax/smaller masses than in |

45170 | the speckle-spectroscopic study by Mason et al. (1996AJ....112..276M). |

45571 | Speckle observations needed to refine relative orbit. |

46404 | Giant primary according to isochrone fit. |

46454 | Giant primary according to isochrone fit. |

47479 | Speckle observations needed to confirm orbit. Sp subsystem in sec? |

49868 | Poorly determined (long) period, only periastron-part covered. |

51233 | G8III-IV spectrum. |

51986 | Visual primary is 10d SB2 (#623 in Batten et al., 1989PDAO...17....1B). |

53423 | F2III classification probably erroneous. |

53840 | Probably 4-5 year period, more speckle observations needed. |

54061 | Low incl. fixed at 180 deg, observations lacking near periastron. Giant |

54061 | primary according to isochrone fit. |

54155 | A-BC triple solution. |

55203 | Preliminary Keplerian Aa-B 2-orbit model gives good solution (failure in |

55203 | HIP). Many-body perturbations observable but not yet studied. Cf. Aa-Bb |

55203 | analysis in Mason et al. (1995AJ....109..332M). |

55266 | Primary is 2.6d SB1 (#669 in Batten et al., 1989PDAO...17....1B). |

55266 | Mass-sum in fair agreement with Liu et al. (1997ApJ...485..350L) |

55425 | A few more speckle obs needed to constrain the eccentricity. |

59816 | Indeterminate (long) period, useable a^3^/P^2^. Poor HIP parallax |

60129 | Observed parallax corroborates closely the orbital value given by |

60129 | Hartkopf et al. (1992AJ....103.1976H). Primary is 72d SB2 (#718 in |

60129 | Batten et al., 1989PDAO...17....1B). |

64241 | Components reversed rel std sol:s, e.g. in Hartkopf et al. |

64241 | (1989AJ.....98.1014H). Poor HIP sol. |

65026 | Marginal hints that the the unconfirmed speckle 3:rd comp (Hartkopf et |

65026 | al., 1997, CHARA Contr. No. 4, (on-line electronic version)) could be |

65026 | real. Mass-sum and mass-ratio (Heintz, 1969AJ.....74..768H) clearly |

65026 | requires the primary to be a closer binary. |

65343 | Undetermined (long) period in nearby K-dwarf pair. |

66458 | A7III spectrum. |

70327 | A-BC triple solution (double A-(BC) in HIP). |

70973 | Double-period, circular orbit ruled out by speckle obs. |

71683 | Difficult for Hipparcos with secondary (=HIP 71681) at edge of the |

71683 | sensitivity profile. Present parallax preferable to HIP value. |

71683 | Mass-ratio from Kamper and Wesselink (1978AJ.....83.1653K). |

72479 | Double-period solution ruled out by speckle observations. |

73182 | Hipparcos triple solution together with A (=HIP73184). P,T,e,{omega} and |

73182 | q fixed from Duquennoy and Mayor (1988A&A...200..135D), cf orbit in |

73182 | Mariotti et al. (1990A&A...230...77M). Poor HIP-sol. |

73695 | Secondary is 0.27d W UMa ecl. bin. |

74537 | Unresolved by speckle(?), no easy vis+Hipparcos sol. |

75411 | More speckle-obs needed to confirm preliminary orbit |

75529 | More observations needed to define (~20-year) orbit. |

75695 | The speckle-observations and derived masses leave no room for a |

75695 | conjectured third component, cf. Kamper et al. (1990AJ....100..239K). |

76852 | Half-period orbit ruled out by speckle-obs. |

76952 | Speckle orbit in Hartkopf et al. (1989AJ.....98.1014H). |

78662 | AB-C triple solution (AB in HIP). |

78727 | AB-C triple solution. (Failed HIP sol because of bad pointing with |

78727 | C-comp at IFOV edge). |

80199 | Poorly determined period, needs many decades yet. |

80460 | Strong a/e-correlation, more speckle-obs needed. |

81693 | No evidence in the speckle or Hipparcos data for the large-ampl |

81693 | third-body orbit given by Baize (1976A&AS...26..177B). Giant primary |

81693 | according to isochrone fit. |

82817 | Flare M-dwarf (V1054 Oph). Mass-ratio and mass-sum requires secondary to |

82817 | be a closer sp bin. Unuseable HIP solution. |

83838 | Speckle orbit in Hartkopf et al. (1989AJ.....98.1014H). |

84012 | Difficult a/e correlation, needs 20 more years of speckle obs. |

84123 | Poor HIP sol. |

84140 | Poor HIP-solution, speckle orbit in Hartkopf et al. (1996AJ....111..370H) |

84425 | (New) orbit based on few observations, mass-sum too small. |

84709 | Good double-sol instead of unuseable HIP-data. |

84949 | Period fixed from sp. orbit. Visual secondary is 2.2d ecl bin (V819 Her). |

84949 | Mass-sum in agreement with Scarfe et al. (1994AJ....107.1529S) |

85141 | High mass-sum, sp duplicity? Speckle orbit in Hartkopf et al. |

85141 | (1996AJ....111..370H). |

86221 | AB-C triple solution. |

87204 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

87655 | Pr is 0.80d W UMa ecl. bin (V 2388 Oph). Speckle orbit in Hartkopf et |

87655 | al. (1996AJ....111..370H). |

88404 | Primary giant according to isochrone fit. |

88637 | Triple sol with C (HIP 88639). Pr is 0.88d ecl. bin (V 772 Her). |

88932 | Poor fit for visual observations, speckle needed. Poor HIP sol. |

89908 | Almost rectilinear relative motion, long period!. |

89937 | P,e fixed from spectroscopy (Tomkin et al., 1987AJ.....93.1236T). |

91394 | Speckle orbit in Hartkopf et al. (1989AJ.....98.1014H). |

91395 | Unobserved periastron can be covered by speckle in near future. |

94056 | More observations needed to define orbit. |

94252 | A-BC triple solution. |

94739 | Strange (but useable) reference point for the Transit Data due to |

94739 | reversed signs for proper motions in the Hipparcos Input Catalog. |

95995 | Spurious HIP-sol for fast-moving 1.35 y pair. SB2-sol in Batten et al., |

95995 | 1989PDAO...17....1B(# 1162), speckle-spectroscopic orbit worthwile. |

96907 | Apastron poorly covered. Speckle orbit in Hartkopf et al. |

96907 | (1996AJ....111..370H). |

97237 | Indeterminate (long) period but useable a^3^/P^2^. Missing in HIP |

97237 | because of poor Input Catalogue position. |

98001 | One component is 155d SB1 (#1187 in Batten et al., 1989PDAO...17....1B). |

98416 | Orbit in Hartkopf et al. (1996AJ....111..370H). |

101227 | More speckle obs needed to cover the orbit. |

101750 | Visual primary is 0.28d W UMa ecl. bin (VW Cep). |

101769 | al. (1989AJ.....98.1014H). |

101955 | Visual primary is 920d SB2 (#1253 in Batten et al., 1989PDAO...17....1B). |

101958 | Speckle orbit in Hartkopf et al. (1989AJ.....98.1014H). |

102782 | Triple solution together with C (102784), which is clearly optical with |

102782 | a faulty HIP position. |

103655 | Visual primary is 3.3d SB2 (#1280 in Batten et al., |

103655 | 1989PDAO...17....1B). |

104858 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

105200 | Pr is 4.0d SB2. Mass-sum in good agreement with the complete |

105200 | speckle-spectroscopic analysis (Fekel et al., 1997AJ....113.1095F). |

105431 | One component is 2.2d SB1 (#1297 in Batten et al., 1989PDAO...17....1B) |

106255 | 1.9 y (circular) astrometric orbit by McNamara et al. |

106255 | (1987AJ.....93.1245M) combined with one speckle obs (Blazit et al., |

106255 | 1987A&AS...71...57B) gives too high mass-sum for this M-dwarf binary. |

106255 | More (IR) speckle needed. |

106811 | Marginal detection of 14:th mag secondary, but mass-sum too large and |

106811 | more GB obs needed to define orbit. (HIP sol is slit-error). |

107354 | Visual secondary is 6.0d SB1 (#1329 in Batten et al., |

107354 | 1989PDAO...17....1B). Speckle orbit in Hartkopf et al. |

107354 | (1989AJ.....98.1014H). |

107522 | Double-period orbit almost as good fit, but in both cases probable |

107522 | secondary sub-system. Speckle and spectroscopic obs needed. |

107788 | Giant (F2 III-IV) class. probably wrong. Speckle orbit in Hartkopf et |

107788 | al. (1989AJ.....98.1014H). |

108431 | Illustrative solutions with useable astrometric mass-ratios. Short-P |

108431 | solution marginally better, but indeterminate with strong |

108431 | element-correlations. Probably giant primary, more speckle-data needed. |

110548 | Long period (almost linear motion in definitely physical system). |

111293 | Wrong object observed by Hipparcos. |

111314 | Giant (A9 III) classification probably wrong. |

111805 | Visual sec. is 552d SB2 (Duquennoy, 1987A&A...178..114D). Speckle orbit |

111805 | in Hartkopf et al. (1996AJ....111..370H). |

111965 | Long-period (circular) orbit prefered, but strangely low mass-sum, |

111965 | probably still underestimated a. |

111974 | Primary giant according to isochrone fit. Speckle orbit in Hartkopf et |

111974 | al. (1989AJ.....98.1014H). |

112915 | Giant (K5III) classification probably wrong. |

113048 | Visual primary is 24d SB1 (#1406 in Batten et al., 1989PDAO...17....1B) |

113445 | Edge-on system, most speckle-obs `wrong' quadrant. |

113996 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

114222 | Visual primary (G2 III) is 557d SB1 (#1425 in Batten et al., |

114222 | 1989PDAO...17....1B). |

115126 | Triple solution with B (HIP 115125) instead of poor HIP-sol. Pr |

115126 | overmassive, probably sp. bin., cf. McAlister and Hartkopf |

115126 | (1982PASP...94..832M). |

116849 | Speckle orbit in Hartkopf et al. (1996AJ....111..370H). |

117570 | High but rather imprecise mass-sum. |
