WDS 20577+2624 RAO 24 (HD 199598) : NOTES
 
 
discov_num notes refcode
RAO 24 A new 0".6 binary detected by Robo-AO. It was targeted because of its .
variable velocity (Nordstrom et al. 2004) and astrometric N rd2004
acceleration (Makarov & Kaplan 2005). The binary is confirmed here, M kr2005
helped by the large PM of the primary. Our photometry places B above .
the MS. According to Guillout et al. (2009 A&A 504, 829), the target .
is young, so its companion could indeed be a PMS star. The object was .
already targeted by Metchev & Hillenbrand (2009) in their survey of M et2009
young stars, but the binary was not detected. After learning of our .
discovery, Metchev was able to extract a measurement of the star from .
the archival data (S. Metchev 2015, private communication). R br2015d
