## Mass determination of astrometric binaries with Hipparcos## II. Selection of candidates and results
In a previous paper (Martin et al., 1997) we have shown that for
double stars with orbital periods smaller than about 25 years, it was
possible to determine from the Hipparcos data, the mass ratio
