Light Curves of Planetary Transits: How About Ellipticity?

  • Carolina von Essen (a1), Klaus F. Huber (a1) and Jürgen H. M. M. Schmitt (a1)
Abstract

The observation of transit light curves has become a key technique in the study of exoplanets, since modeling the resulting transit photometry yields a wealth of information on the planetary systems. Considering that the limited accuracy of ground-based photometry does directly translate into uncertainties in the derived model parameters, simplified spherical planet models were appropriate in the past. With the advent of space-based instrumentation capable of providing photometry of unprecedented accuracy, however, a need for more realistic models has arisen.
