HS 1136+6646 = WD 1136+667. The A component is a hot young DAO white |
Lie2006 |
|
dwarf plus K7V in a close detached binary. The wider companion is seen |
|
|
in SDSS and HST/STIS images, and is estimated to be of spectral type |
|
|
K4-5V. Similar proper motion of the close pair and the companion |
|
|
during the 3.84 years between images leads the authors to conclude the |
|
|
companion is probably physical. |
