CHR 96 |
Aa,Ab: 1985.8396, 1988.6630, 1989.7061: These new observations were |
|
|
found from reprocessing unpublished archival data. We are currently |
McA1993 |
|
undertaking a duplicity survey of all bright (V<8) galactic O stars; |
|
|
this is one of four new binaries found by us so far in this survey. |
McA1987a |
|
This system is also a known spectroscopic binary, and we are |
|
|
reanalyzing archival radial velocity data in an attempt to derive |
|
|
masses via a combined interferometric/spectroscopic orbit (see Gies et |
Gie1993 |
|
al. 1993 for a similar combined solution of the O star 15 Mon). |
|
|
The estimated period of the speckle binary orbit (CHR 96 Aa) is 31 y. |
|
|
The orbit quality rating in Table 1 is our own. The system is |
|
|
currently unresolved with the Mt. Wilson Hooker telescope, but we |
|
|
continue to observe this target. The brighter star of the speckle |
|
|
pair is also a 311-day, single-lined spectroscopic binary (McKibben et |
Bgn1998 |
|
al. 1998). The classifications of the C and D components are from |
Hof1991 |
|
Hoffleit & Warren (1991). |
Msn1998a |
|
Cluster/Main-Sequence fitting determines a cluster distance of |
Rbr2010b |
|
741 +/- 36 pc. |
|
CHR 96 |
ten Brummelaar et al. (2011) use a combination of spectroscopic and |
CIA2011b |
CIA 6 |
astrometric data, including speckle and CHARA Array long-baseline |
|
|
interferometry, to derive orbits for both the Aa,Ab and Ab1,Ab2 pairs. |
|
|
Masses for Aa, Ab1, and Ab2 are 21, 23, and 9 Msun, respectively, |
|
|
effective temperatures are 33, 32.5, and 20 kK. |
|
|
Distance to Collinder 419 is 1006(+37-34) pc, yielding a mass sum of |
MzA2019b |
|
76.1(+9.9-7.4) \msun. |
