phi And = 42 And. Measure of 1985.830 made by MAPPIT. |
Han1987 |
|
Scardia et al. (2001) orbit considered preliminary. The real period |
Sca2001d |
|
is probably long (>400 yr). The Hipparcos parallax is 0".00443 +/- |
|
|
0.00080, giving a mass sum of 6.9 Msun, slightly in excess for a |
|
|
binary of spectral type B7Ve. The dynamical parallax is 0".0033, in |
|
|
reasonable agreement with the measured one but not acceptable as it |
|
|
leads to an exaggerated mass sum (16.8 Msun). |
|
|
Calculated mass sum is 6.5 +/- 2.8 Msun, in reasonable agreement with |
|
|
spectral types B6IV and B9V, although mass is not well-constrained. |
