DUN 65 | A: gam 2 Vel. Spectrum WC8+O7.5e, probably the nearest Wolf Rayet. | |
B: gam 1 Vel. CD-46@3846. Variable, spectrum B1IV. | ||
AB: Both components are spectroscopic binaries. | ||
The AB pair was formerly known as DUN 64. | ||
I 1175 | DE: DE is I 1175 (= RST 4878) at 08 09.5 -47 25. | |
The Hipparcos distance suggests a position in front of the Vel OB2 | ||
association (van der Hucht et al. 1997 NewA 2, 245; Schaerer et al. | ||
1997 ApJ 484, L153) at a distance of 258 +41/-31 pc; however, the | ||
Hipparcos distances for the B stars in Vel OB2 (Brandt et al. 1971 ApJ | ||
1623, L99) yield a comparable distance of 317 +/- 42 pc. This is also | ||
consistent with the distance from the resolution of the binary by | ||
Hanbury Brown et al. (1970) of 350 +/- 50 pc. Thus, we have chosen to | HBr1970 | |
keep gam 2 Vel as a member of Vel OB2. Classification is from van der | ||
Hucht et al. (1997). The B component was also observed and appeared | ||
to be single. Classifications of the B, C, and D components are from | Msn1998a | |
Hoffleit & Warren (1991). | Hof1991 | |
TOK 2 | Aa: The primary is a close WR+O binary. Although the pair is | |
unresolved, VLTI/AMBER observations on 2004.984 over baselines of | ||
46-85m and wavelength range 1950-2170 nm are fit by a binary model | ||
giving a separation of 3.65 +/- 0.06 mas, position angle 72.7 +/- 8.7 | ||
deg, flux ratio 0.62 +/- 0.04 (dm 0.52 +/- 0.07 mag. | MiF2007 | |
Intensity Interferometer Limb-darkened diameter 0.44 +/- 0.05 mas. | HBr1974 |
