KR 60 B is the flare star DO Cep, which is fairly active with flares of small
to moderate amplitudes.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
AC, AE, AF, and AI: Optical pair, based on study of relative motion of
the components using the method of apparent motion parameters. Kiy2008
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 0.43 +/- 0.06, 0.42, and 0.56 Msun, respectively. Mlk2012
HZE 5 Heinze et al. (2010) determine the K component is a background object. Hze2010
FYM 118 The EQ pair was initially listed incorrectly as CQ. The CD pair was
initially listed incorrectly as a new CT pair. FyM2014b
