TOK 195 Astrometric binary; dm 1.0 mag, period ~ 7.0y Orbit (Jancart et al. Jnc2005
2005), SB1 Tok2012b
The bright star a Pup (HD 64440, HR 3080) is known as a spectroscopic
binary. However, examination of the RV data reveals that the orbit by
Parsons (1983 ApJS 53, 553) is only approximate. The binary is
difficult to measure, always close to the diffraction limit and with
dm~3. Instead of the spectroscopic period of 6.99yr, our orbit has
P=7.4y and is still preliminary. More RV coverage is obviously needed. Tok2015c
