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found from reprocessing unpublished archival data.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. |
