- Abstract
In general, in the studies of transit light-curves and the Rossiter-McLaughlin (RM) effect, the contribution of the planet's gravitational microlensing is neglected. Theoretical studies, have, however shown that the planet's microlensing can affect the transit light-curve and in some extreme cases cause the transit depth to vanish. In this paper, we present the results of our quantitative analysis of the contribution of microlensing on the RM effect. Results indicate that for massive planets in long-period orbits, the planet's microlensing will have considerable contributions to the star's RV measurements. We present the details of our study, and discuss our analysis and results.
