HJ 1535 | AB: A is SB1 (CfA: P=1342d = 3.67y) and astrometric binary (Goldin & | Gln2007 |
Makarov 2007, P=1437d) | Tok2014d | |
AC and AD: Optical pairs, based on study of relative motion of the | ||
components using the method of apparent motion parameters. | Kiy2008 | |
A new 2+2 quadruple system. The outer 17" binary HJ 1535 AB has been . | ||
known since 1828 (Herschel 1831). If B were a background star, the PM H | J_1831 | |
of A, 0".208/y, would have moved it by 38" in 185 yr. The pair AB is . | ||
therefore undoubtedly physical. The discrepant PM of B reported in . | ||
the WDS could be caused by the subsystem Ba,Bb discovered here. The A . | ||
component has an astrometric subsystem Aa,Ab with P = 3.9 yr (Goldin . | ||
& Makarov 2007), confirmed spectroscopically by D. Latham. The B G | ln2007 | |
component was tentatively resolved by Robo-AO, but was thought to be . | ||
too uncertain to publish in Riddle et al. (2015). Now Ba,Bb is R | AO2015 | |
clearly resolved at 0".17. Its estimated period is ~30 yr. The field . | ||
is extremely crowded and another faint star E is detected at 12".1 . | ||
from A by both Robo-AO and PALM-3000. Comparison with 2MASS shows . | ||
relative motion opposite to PM(A), so AE is optical. R | br2015d | |
