HIP 7601 is a nearby (27pc) dwarf also known as GJ 67.1 or HR 512. |
|
|
According to Wichman et al. (2003 A&A, 400, 293), it is a young |
|
|
spectroscopic triple detected in X-rays (1RXS J013755.4-825838). GCS |
|
|
also recognized the star as SB2. Spectroscopic monitoring (Tokovinin, |
|
|
in preparation) shows that all three components are similar stars of |
|
|
approximately one solar mass. Here we resolved the outer subsystem AB |
|
|
and observed its fast motion. In fact it was already resolved at SOAR |
|
|
on 2011.036 at 221.0deg and 0".044, but this low-quality observation |
|
|
has not been published. The available data indicate that the period |
|
|
of AB is 1.35years; the pair completed nearly two revolutions since |
|
|
its first resolution in 2011. |
