STF 115 | First measured by F.W. Struve in 1836 at an angular separation of | Hrt1989 |
0".68, this system had opened to 1".2 by 1910, then steadily closed | ||
to 0".35 at the time of the first speckle measurement in 1978. | ||
The pair reached an apparent minimum separation of 0".01 in the | ||
spring of 1984. | ||
1983.7107 This autocorrelogram was remeasured; the new results are | ||
listed in the catalog. | ||
AB: Malkov et al. (2012) derive dynamical, photometric, and | ||
spectroscopic masses 2.36 +/- 0.67, 2.80, and 1.20 Msun, respectively. | Mlk2012 |
