MCA 19 115 Tau. A is an occultation binary which has been resolved by
speckle interferometry.
First detected as an occultation binary by Africano. Afr1978
1982.7551: All archival data for this system were reprocessed using
more powerful algorithms than earlier available, resulting in four new
unresolved measures as well as the new 1991 measurement. In addition,
new rho and theta values have been determined for the observations McA1989
originally published from 1986.9-1988.3 (McAlister et al. 1989), McA1990
1988.7-1989.2 (McAlister et al. 1990), and 1990.3--1990.8 (Hartkopf Hrt1992b
et al. 1992). A preliminary orbit gives a period of ~15.3 years and
a semi-major axis of 0".080. Hrt1994
1988.2518: This date was incorrectly given as 1988.2490 in McAlister
et al. (1989). McA1989
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 6.46 +/- 2.35, 8.01, and 4.79 Msun, respectively. Mlk2012
