1 | binary. |
2 | New debris disk candidate. |
3 | Caution: IRAS SCANPI shows high background fluctuation near IRAS 60 micron |
3 | detection. |
4 | HIP 7345 (=49 Cet) is the only known main sequence A-type star with CO |
4 | emission detected with a radio telescope (ZFK), thus suggesting a very young |
4 | age. But its galactic space motion UVW (-23,-17,-4) with respect to Sun is |
4 | not indicative of extreme youth (U is positive toward the Galactic center). |
5 | HIP 8241 shows the age of the Pleiades on an A star HR diagram Lowrance et |
5 | al. (2000ApJ...541..390L) but of the Hyades in UVW measurements. |
6 | There is a galaxy at ~48" East of HIP 13005 in cross-scan direction as |
6 | described in Paper I (Zuckerman, & Song, 2004ApJ...603..738Z). However, a |
6 | more careful check of the IRAS 60 micron offset using the FSC long format |
6 | indicates that both IRAS 12 micron and 60 micron detections have the same |
6 | offsets away from the galaxy in the same cross-scan direction. Thus, we |
6 | include HIP 13005 with a caution. |
7 | No age estimate is given for HIP 14576, HIP 96468, & HIP 110867. |
8 | Eclipsing binary of the Algol type. |
9 | Spectroscopic binary. |
10 | Caution: IRAS SCANPI shows >30" offset IRAS 60 micron detection from the |
10 | stellar position in in-scan direction. |
11 | There are two FSC detections for HIP 19704 separated by 34" in the in-scan |
11 | direction. One has 12 and 25 micron detections, the other has a 60 micron |
11 | detection. The long format of FSC locates the 60 micron source on HIP 19704. |
12 | In addition to the point-like 60 micron source reported in the FSC, there is |
12 | an extended optical source 70" from the IRAS position of HIP 19893 in the |
12 | in-scan direction. Jura et al. (2004ApJS..154..453J) found no strong excess |
12 | up to 35 micron in this star. Thus the IRAS excess at 60 micron should be |
12 | regarded with caution. |
13 | Caution: there is a galaxy 90" East of HIP 22439. |
14 | Caution: there is a galaxy 55" East of the FSC position at the 3{sigma} edge |
14 | of the error ellipse, mostly in the cross-scan direction. |
15 | Caution: IRAS FSC detection is 40" West of HIP 27980, and IRAS SCANPI profile |
15 | is very broad. |
16 | Caution: there is a galaxy 58" away from the IRAS position of HIP 28230 in |
16 | the cross-scan direction. |
17 | There is a ROSAT All-Sky Survey X-ray source ~44" from HIP 32480, but UVW |
17 | indicates an old age. |
18 | Location on A-star HR diagram near HR 4796 is suggestive of a 10Myr age, but |
18 | the V component of UVW (-16,-44,-9; Moor et al. 2006ApJ...644..525M) is |
18 | quite unlike that of most very young stars. |
19 | HIP 42430 is a 1.0" binary. |
20 | Caution: SCANPI shows a bad profile fit to the 60 micron source. |
21 | Kouwenhoven et al. (2005A&A...430..137K) say HIP 53524 and HIP 61782 are LCC |
21 | members. |
22 | Caution: IRAS SCANPI shows no source detection. |
23 | The M-star companion LDS 2662 to HIP 63584 is very young based on its |
23 | location on an M_K versus V-K color magnitude diagram (e.g., Figure 2 in |
23 | SZB, Song et al., 2003ApJ...599..342S). |
24 | Moor et al. (2006ApJ...644..525M) rejected HIP 69682 based on a nearby 2MASS |
24 | source with an excess in the K_s_-band. However, no NED identified extended |
24 | source exists within 2' from this star and the FSC long format indicates |
24 | that the 60 micron detection falls on the star itself. The Galactic space |
24 | motion (UVW) and absence of lithium and of X-ray emission all point to an |
24 | old star. There is no evidence on the Digital Sky Survey and 2MASS All Sky |
24 | QuickLook Images (JHK_s) of a nearby galaxy. Yet {tau} is very large. |
25 | HIP 73145 is an Upper Centaurus Lupus member. |
26 | HIP 73473 has significant X-ray flux. |
27 | Caution: there exists a large galaxy at ~80" East of HIP 76375. |
28 | Moor et al. (2006ApJ...644..525M) rejected HIP 77163 & HIP 83480 based on |
28 | their location near the wall of the Local Bubble. |
