New observable for gravitational lensing effects during transits

Earth and Planetary Astrophysics 2015-05-19 v2

Abstract

We investigate gravitational lensing effects of an extrasolar planet transiting its host star. We focus on the `rising spikes' of the light curve just before and after the transit, which is a peculiar feature of the gravitational lensing, and find that it could be a novel observable for determining physical parameters. Detectability of such an effect is also discussed.
