MCA 8 12 Per. SB2 resolved by speckle interferometry by McAlister (1977). McA1977
Elements P = 331.0d, T, e, and longitude of periastron for McAlister McA1978a
solution are from the spectroscopic orbit by Colacevich (1941). Cla1941
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Colacevich (1941).
Martin et al. (1998) derive component masses 1.125 +/- 0.169 and
1.389 +/- 0.193 Msun. Mig1998
Pourbaix gives combined solution for this resolved SB2, yielding
orbital parallaxes and component masses. Pbx2000b
Bagnuolo et al. (2006) solution combines speckle data with data from Bgn2006
the CHARA Array. Authors derive orbital parallax 41.19 +/- 0.21 mas,
masses 1.382 +- 0.019 and 1.240 +- 0.017 Msun, and a magnitude
difference 0.409 +/- 0.013 mags in K' (2136 nm). Values for omega and
Omega are switched in their Table 3.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.59 +/- 3.80, 2.58, and 1.07 Msun, respectively. Mlk2012
