SHY 753 |
HIP 95203 + HIP 95164. |
|
|
AB + TOK 423Aa,Ab: HIP 95203 is another acceleration binary with |
|
|
variable RV resolved here. The relatively large separation of 0".77 |
|
|
corresponds to a period of ~180yr. The actual period can be as short |
|
|
as 60yr if the pair is seen now near its maximum separation (it would |
|
|
then have been closer at the time of the Hipparcos mission). Most |
|
|
likely, however, the faint visual companion found here and the |
|
|
spectroscopic/acceleration pair make a triple system. There is another |
|
|
companion HIP 95164 at 435". The status of this wide pair (is it a |
|
|
real binary or just two members of a moving group?) is not clear, but |
|
|
the association of those stars leaves no doubt (common RV, PM, and |
|
|
parallax). |
