Planetary Mass Determinations from a Simplified Photodynamical Model -- Application To The Complete Kepler Dataset
Aviv Ofir, Gideon Yoffe, Oded Aharonson
We use PyDynamicaLC, a model using the least number of, and the least correlated, degrees of freedom needed to derive a photodynamical model, to describe some of the smallest -- an…
