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
