WDS 10067+1754 HDS 1457 AB (HD 87646) : NOTES
 
 
discov_num notes refcode
HDS1457 The primary is a bright G-type star, mass 1.12 +/- 0.09 Msun, radius
1.55 +/- 0.02 Rsun, Teff 5770 +/- 80K. Hipparcos gives a parallax of
13.59 +/- 1.58 mas (73.58 +/- 9.68pc). Ma et al. (2016) resolve two MaB2016
close companions, in addition to the HDS companion, and determine some
orbital elements for all three pairs. The Ab companion is likely a
giant planet or brown dwarf, depending on the inclination angle;
mimimum mass is 12.4 +/- 0.7 Mjup. The Ac companion is likely a brown
dwarf; minimum mass 57.7 +/- 3.7 Mjup. The closest companion appears
to be new, so is given the designation MAB 2Aa,Ab. The Ac component
has a separation similar to the unconfirmed companion measured by
Balega et al. (2006) in 2001, so the BAG 23 designation is retained, Bag2006b
although the component pair is changed to Aa,Ac to match that of Ma.
