A dynamical mechanism for establishing apsidal resonance | | Renu Malhotra
; | | Date: |
4 Jul 2002 | | Journal: | Astrophys.J. 575 (2002) L33-L36 | | Subject: | astro-ph | | Abstract: | We show that in a system of two planets initially in nearly circular orbits, an impulse perturbation that imparts a finite eccentricity to one planet’s orbit causes the other planet’s orbit to become eccentric as well, and also naturally results in a libration of their relative apsidal longitudes for a wide range of initial conditions. We suggest that such a mechanism may explain orbital eccentricities and apsidal resonance in some exo-planetary systems. The eccentricity impulse could be caused by the ejection of a planet from these systems, or by torques from a primordial gas disk. The amplitude of secular variations provides an observational constraint on the dynamical history of such systems. | | Source: | arXiv, astro-ph/0207126 | | Services: | Forum | Review | PDF | Favorites | |
