Seven SB2 masses using Hipparcos intermediate astrometric data

Abstract : The spectroscopic orbital elements of seven double-lined spectroscopic binaries have been combined with the Hipparcos astrometric data. Dynamical masses and magnitude differences are determined with a precision of about 15% on average, and the astrometric parameters are improved.
