The Hipparcos observations and the mass of sub-stellar objects.


Abstract (from CDS):

The Hipparcos Intermediate Astrometric Data have been used lately to estimate the inclination of the orbital plane of candidate extrasolar planets. Whereas most of these investigations derive almost face-on orbits, we show that the astrometric data are seldom precise enough to undertake such studies and that the ``face-on'' result might be just a spurious effect of the method.
