MCA 36 A spectroscopic binary and suspected occultation binary now resolved
by speckle interferometry.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Ginestet et al. (1985). Gin1985
The pair has been resolved 3 times 1980-1994, but unresolved ~35 times HIP1997d
1980-1998. Published astrometric orbits give a period of ~1.3y and an Jnc2005
inclination near 90deg. Hrt2009
Ren & Fu (2013) calculated an astrometric orbit, combining Hipparcos Ren2013
Intermediate Astrometric Data with spectroscopic elements by
Imbert & Carquillat (2005). Crq2005
