Polarization of Starlight by an Unresolved and Oblate Extrasolar Planet in an Elliptical Orbit

open access: yesThe Astrophysical Journal, 2006
We calculate the degree of linear polarization of radiation from stars having planets that may not be resolved spatially. We assume single scattering by water and silicate particulates in the planetary atmosphere. The dilution of the reflected polarized radiation of the planet by the unpolarized stellar radiation and the effect of oblateness of the ...

Twist and non-twist regimes of the oblate planet problem

open access: yesRendiconti Lincei, Matematica e Applicazioni, 2017
We consider the dynamics of a point-mass object, e.g. a small satellite, around a primary rigid body, e.g. a planet. We assume that the planet is oblate and axially symmetric with respect to the vertical axis. Revisiting a procedure described in [19], we make use of the first integrals (the energy and the projection of the angular momentum on the ...

Analytic Model for The Motion About An Oblate Planet in The Presence Atmospheric Drag

open access: yes, 2015
The paper introduces a new model for the motion about an oblate planet under the influence of the atmospheric drag. Both qualitative and quantitative insights are revealed, as well as closed-form equations of motion.
