RAO 9 | AB: Primary is HIP 12925. A 13.8m star at 221.7deg, 494.3" appears to | |
share common proper motion, but the probability of physicality is only | ||
36%. It is likely this star is another member of the Tuc-Hor moving | ||
group. HIP 12925 and 12862 also appear to be a co-moving pair. | Tok2013c | |
AB: The primary is a spectroscopic binary. | Tok2014d | |
Quadruple system with 3-tier hierarchy: a close spectroscopic pair | ||
with yet unknown period, Robo-AO companion D at 1".89, and CPM | ||
companion C at 494" (Tokovinin & Lepine 2012). Yet another star, | Tok2012c | |
HIP 12862, at 0.9deg, also shares common PM and parallax. The stars | ||
are young and belong to the Tucana–Horlogium moving group (Zuckerman | ||
et al. 2011 ApJ 732, 61). Our photometry places D slightly above the | ||
MS. D was independently discovered by Brandt et al. (2014) by high- | Bdt2014 | |
contrast imaging at Subaru. They measured it on 2012.0 at 252.9 deg | RAO2015 | |
and 1".893, in excellent agreement with Riddle et al. (2015). | Rbr2015d | |
TOK 651 | AC: Tuc-Hor moving group? Additional CPM companions at 725" and 1536". | Tok2014d |
AD: Too wide to be a companion at 3271", but CPM, common parallax. F | ||
is a rapid rotator (Vsini=109km/s), on main sequence. |
