Analysis of the Hipparcos measurements of υ Andromedae: a mass estimate of its outermost known planetary companion.
MAZEH T., ZUCKER S., DALLA T.A. and VAN LEEUWEN F.
Abstract (from CDS):
We present an analysis of Hipparcos astrometric measurements of υ Andromedae, a nearby main-sequence star around which three planet candidates have recently been discovered by means of radial velocity measurements. The stellar orbit associated with the outermost candidate has a period of 1269±9 days and a minimum semimajor axis of 0.6 mas. Using the Hipparcos data together with the spectroscopic elements, we found a semimajor axis of 1.4±0.6 mas. This implies a mass of 10.1+4.7–4.6 Jupiter masses for that planet of υ And.
