AGC 13 tau Cyg = 65 Cyg.A is a Delta Scuti-type variable.
Spectral types and masses of components assigned by ten Brummelaar et
al., based on adaptive optics observations. TtB2000
Identification of the ascending node is probable although small
variations of non-orbital origin superimpose on the RV. A is a Delta
Scuti-type variable. A faint star listed as component F is physical;
linear formula given by Heintz.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
AC and AB,D: Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
AB: The Soderhjelm (1999) orbit predicts a separation of 0.734", but Sod1999
the magnitude difference (published value 2.7mag) may have been too
great. Hrt2009
Calculated mass sum is 2.63 +/- 0.12 Msun. There is some indication of
a substellar companion orbiting one of the two stars, but this is
uncertain. This solution uses only a single Keplerian model. Mut2010b
AC: Rectilinear solution by Hurowitz et al. (2014). USN2014b
