Abstract

Observations of about 60 binary star systems hosting exoplanets indicate

the necessity of stability studies of planetary motion in such

multi-stellar systems. For wide binary systems with separations between

hundreds and thousands of AU, the results from single-star systems may

be applicable but, in tight double stars systems, we have to take the

stellar interactions into account which influences the planetary motion

significantly.

This review discusses the different types of planetary motion in double

stars and the stability of the planets for different binary

configurations. An application to the most famous tight binary system

(γ Cephei) is also shown. Finally, we analyze the habitability

from the dynamical point of view in such systems, where we discuss the

motion of terrestrial-like planets in the so-called habitable zone.
