Eccentricity generation in hierarchical triple systems: the planetary regime

Earth and Planetary Astrophysics 2014-08-28 v1

Abstract

In previous papers, we developed a technique for estimating the inner eccentricity in hierarchical triple systems, with the inner orbit being initially circular. We considered systems with well separated components and different initial setups (e.g. coplanar and non-coplanar orbits). However, the systems we examined had comparable masses. In the present paper, the validity of some of the formulae derived previously is tested by numerically integrating the full equations of motion for systems with smaller mass ratios (from 103\mboxto103{10^{-3} \hspace{0.2cm} \mbox{to} \hspace{0.2cm} 10^{3}}, i.e. systems with Jupiter-sized bodies). There is also discussion about HD217107 and its planetary companions.
