Stellar wobble caused by a binary system: Can it really be mistaken as an extra-solar planet?

MORAIS M.H.M. and CORREIA A.C.M.

Abstract (from CDS):

The traditional method for detecting extra-solar planets relies on measuring a small stellar wobble which is assumed to be caused by a planet orbiting the star. Recently, it has been suggested that a similar stellar wobble could be caused by a close binary system. Here we show that, although the effect of a close binary system can at first sight be mistaken as a planetary companion to the star, more careful analysis of the observational data should allow us to distinguish between the two effects.
