1binary.
2New debris disk candidate.
3Caution: IRAS SCANPI shows high background fluctuation near IRAS 60 micron
3 detection.
4HIP 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).
5HIP 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.
6There 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.
7No age estimate is given for HIP 14576, HIP 96468, & HIP 110867.
8Eclipsing binary of the Algol type.
9Spectroscopic binary.
10Caution: IRAS SCANPI shows >30" offset IRAS 60 micron detection from the
10 stellar position in in-scan direction.
11There 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.
12In 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.
13Caution: there is a galaxy 90" East of HIP 22439.
14Caution: 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.
15Caution: IRAS FSC detection is 40" West of HIP 27980, and IRAS SCANPI profile
15 is very broad.
16Caution: there is a galaxy 58" away from the IRAS position of HIP 28230 in
16 the cross-scan direction.
17There is a ROSAT All-Sky Survey X-ray source ~44" from HIP 32480, but UVW
17 indicates an old age.
18Location 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.
19HIP 42430 is a 1.0" binary.
20Caution: SCANPI shows a bad profile fit to the 60 micron source.
21Kouwenhoven et al. (2005A&A...430..137K) say HIP 53524 and HIP 61782 are LCC
21 members.
22Caution: IRAS SCANPI shows no source detection.
23The 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).
24Moor 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.
25HIP 73145 is an Upper Centaurus Lupus member.
26HIP 73473 has significant X-ray flux.
27Caution: there exists a large galaxy at ~80" East of HIP 76375.
28Moor et al. (2006ApJ...644..525M) rejected HIP 77163 & HIP 83480 based on
28 their location near the wall of the Local Bubble.
