SEE 219 | AB: lam Lup. | |
Probably a spectroscopic subsystem, as the RV of the combined light | ||
shows a range of 50 km/s. | ||
1976.471: The observed separation is significantly different from the | B__1962c | |
value derived from van den Bos' (1962) preliminary elements. | BLM1978 | |
AB: Hipparcos parallax 4.20 +/- 0.66 mas. Dynamical parallax 6.3 mas, | ||
masses 8.14 and 5.84 Msun. lam Lup is a B3V binary belonging to the | ||
Sco-Cen association. A minor revision of the orbit by Docobo & Ling | Doc2007d | |
(2007) proposed here turns it into a definitive one, with both sides | ||
of the ellipse now covered by speckle measures and one full revolution | ||
observed. The Hipparcos parallax corresponds to an uncomfortably large | ||
mass sum. The true parallax should be around 6 mas, matching the | ||
distance to the association. | Tok2012b |
