TOK 426 | 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. | Tok2015c |
