B 2256 eta Car = Trumpler 16 MJ 480, an old nova in a nebula with nuclei.
I 1092 B and C involved in the nebulosity. B__1951a
WGT 2 One of these three components found by Weigelt is probably B 2256; Wgt1986a
DUN 98 however, it is not clear which one due to the lack of a continuous
series of observations and orbital motion.
This famous luminous blue variable is not classified as an O star, but
it is almost certainly a massive object. The inner structure of the
ejecta of this star is described by Davidson et al (1997 AJ 113, 335).
A preliminary set of orbital elements is given by Damineli et al.
(1997 NewA 2, 107), who suggest a 5.5-yr orbit with a maximum angular
separation of 0".004. The central object appeared single in our
observations. The H component (HDE 303308) was also observed and
appeared to be single. Msn1998a
Powell also measured the distance to 10446-5944BSO 4 (1856.012, Pwl1857
229.57 deg, 294.77; 1860.297, 229.3 deg, 297.8"), but they are not Pwl1864
physically related so are not merged.
Powell also measured the distance to 10441-5935HJ 4360C (1860.306, Pwl1864
312.6 deg, 571.1"), but they are not physically related so are not
merged.
