J/AJ/128/3012      Speckle interferometry at USNO. X.             (Mason+, 2004)

Speckle interferometry at the US Naval Observatory. X. Mason B.D., Hartkopf W.I., Wycoff G.L., Rafferty T.J., Urban S.E., Flagg L. <Astron. J., 128, 3012-3018 (2004)> =2004AJ....128.3012M
ADC_Keywords: Stars, double and multiple ; Interferometry Keywords: binaries: general - binaries: visual - techniques: interferometric Abstract: The results of 3047 speckle interferometric observations of double stars, made with the 26inch (66cm) refractor of the US Naval Observatory, are presented. Each speckle interferometric observation of a system represents a combination of over a thousand short-exposure images. These observations are averaged into 1572 mean relative positions and range in separation from 0.20" to 62.86", with a median separation of 4.19". This is the 10th in a series of papers presenting measures obtained with this system and covers the period 2003 January 13 through 2003 December 1. File Summary:

Note (1): WDS J19456+3337 (=STF2576) is very likely WDS J19464+3344,FG ; corrected by CDS. Note (2): Flag on Ref, defined as follows: * = System used in characterizing errors. 1 = This measure was inconsistent with previous measures and so was not included in Mason et al. (2004, Cat. J/AJ/127/539). However, available data are deemed insufficient for a new orbital calculation at this time. 2 = This system was expected to show significant motion over the calendar year, so multiple observations have been obtained. 3 = Appears to be approaching periastron sooner than expected, and with a more eccentric orbit. The new orbit is listed in Table 5, ephemerides based on these elements are listed in Table 6, and the orbit is illustrated in Fig. 1. 4 = This measure was inconsistent with previous measures and so was not included in Mason et al. (2001, Cat. J/AJ/121/3224). The new orbit is listed in Table 5, ephemerides based on these elements are listed in Table 6, and the orbit is illustrated in Fig. 1.

Note (1): Notes, defined as follows: 1 = Measured twice by Olivier (1909AN....182..253O, 1920AJ.....33...25O) but not seen by any other observer. 2 = Only arcminute coordinates are available for this pair resolved by Pourteau (1933, Catalogue des etoiles doubles de la zone +24° de la Carte Photographique du Ciel (Orleans: H. Tessier)). Because of this, it is not certain that the right star was observed. 3 = Listed as having two measures in the WDS (Baillaud 1943, Ann. Obs. Besancon, 3, 33; Urban et al. 1998, Cat. I/275); however, they are two different measures of the same plate and, possibly, the same plate defect. Not seen since. 4 = Two early 20th-century measures (Lewis 1907, Greenwich Observations; Bowyer 1907, Greenwich Observations) are of a fairly wide system and are quoted here. There is a recent measure by Argue et al. (1992, Cat. J/MNRAS/259/563; 57.0° and 0.69"), which, if real, may explain the lack of resolution by the system's being slow-moving and too close at present. 5 = STN 46 appears to be the same as S 716 with an error in right ascension. See Table 2, note 4. 6 = Measures from Lewis (1901) were assigned to both this pair and 20010+2956 (L 32) in the Burnham (1906; BDS 9785 and BDS 9824) and Aitken (1932; ADS 13233 and ADS 13255) catalogs: Lewis : 1901, Greenwich Observations Burnham: 1906, A General Catalogue of Double Stars within 121° of the North Pole (Carnegie Inst. Washington Publ. 5) (Washington: Carnegie Inst.) Aitken : 1932, New General Catalogue of Double Stars within 121° of the North Pole (Carnegie Inst. Washington Publ. 417) (Washington: Carnegie Inst.) Published coordinates and magnitudes are also similar, and only one pair is seen on POSS plates, leading to the conclusion that these are the same system. The L 32 designation was maintained, as its WDS designation was correct. See Table 2, note 5.
