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. |

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. |
