| 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. |
