Primary is a spectroscopic binary, P = 1033:d. |
|
NOI 3 |
Aa,Ab: Hipparcos astrometric solution adopted some elements from the |
HIP1997d |
|
orbit of Abt & Levy (1978). |
AbH1978 |
|
Koubsky et al. (2010) combined solution uses NPOI astrometric data |
NOI2010 |
|
together with radial velocities from the Dominion Astrophysical and |
|
|
Ondrejov Observatories. The secondary appears to be of similar mass to |
|
|
the primary, although the magnitude difference is nearly 3 magnitudes. |
|
|
One possible explanation might be that the secondary is comprised of a |
|
|
close pair of similar stars, possible early A dwarfs. |
|
|
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and |
|
|
spectroscopic masses 6.12 +/- 2.94, 7.39, and 5.62 Msun, respectively. |
