AB + TOK 420Aa,Ab: The neglected pair YSC 67 turned out to be a new |
|
|
triple. The outer 0".35 binary AB was known previously, now we detect |
|
|
elongation that implies an inner subsystem Aa,Ab. We compared with |
|
|
stars in the same area of the sky observed before and after to assure |
|
|
that the elongation is not of instrumental origin; it is seen in two |
|
|
filters. |
