New observable for gravitational lensing effects during transits

Show Summary Details


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.
