| Seven SB2 masses using Hipparcos intermediate astrometric data (2009) | |||||||||||||
Abstract | |||||||||||||
| The spectroscopic orbital elements of seven doublelined spectroscopic binaries have been combined to the Hipparcos astrometric data. Dynamical masses and magnitude differences are determined with a precision of about 15 % on the average, and the astrometric parameters are improved. 1. | |||||||||||||
