A Novel Eccentricity Parameterization for Transit-only Models.

EASTMAN J.D.

Abstract (from CDS):

We present a novel eccentricity parameterization for transit-only fits that allows us to efficiently sample the eccentricity and argument of periastron, while being able to generate a self-consistent model of a planet in a Keplerian orbit around its host star. With simulated fits of 330 randomly generated systems, we demonstrate that typical parameterizations often lead to inaccurate and overly precise determinations of the planetary eccentricity. However, our proposed parameterization allows us to accurately-and often precisely-recover the eccentricity for the simulated planetary systems with only transit data available.
