DOR 66 del Tri = 8 Tri. A is a double-lined spectroscopic binary, P = 10.02d.
Proper motion +1154 -245.
MKT 5 Aa,Ab: PM = +1154 -245. del Tri.
Hummel et al. 1995) visual orbit based on astrometry from Mark III MkT1995
interferometer. Additional spectroscopic data yield component masses,
luminosities, radii, effective temperatures, and distance.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Hummel et al. (1995). MkT1995
Pourbaix gives combined solution for this resolved SB2, yielding
orbital parallaxes and component masses. Pbx2000b
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.57 +/- 3.14, 1.92, and 1.05 Msun, respectively. Mlk2012
