A is a long-period spectroscopic binary, P = 15000d (?). |
|
BTM 1 |
Aa,Ab: Bottom et al. (2015) resolve the spectroscopic binary del And |
|
|
using the Palomar 5m and Stellar Double Coronograph. The physical |
|
|
separation is 11.55 +/- 0.13 au; the spectral type of the companion is |
|
|
estimated at K4 +/- 2. |

Aa,Ab: Gontcharov & Kiyaeva (2002) orbit based on combination of |
Gon2002b |
|
ground-based catalogs with Hipparcos. They quote masses of 1.3+/-0.4 |
|
|
and 1.3 Msun for the two components, and estimate their spectral types |
|
|
as K3III and white dwarf. |
