Illuminating hot Jupiters in caustic crossing

摘要: In recent years a large number of hot Jupiters orbiting in very close orbit around the parent stars have been explored with transit and Doppler effect methods. Here this paper we study gravitational microlensing binary lens on star Jupiter revolving it. Caustic crossing planet makes enhancements light curve which signature can be detected by high-precision photometric observations. We use inverse ray shooting method tree code algorithm to generate combined planet. order investigate probability observing signal, do Monte Carlo simulation obtain observational optical depth τ ∼ 10 −8 . show that about yr observations Galactic bulge network telescopes will enable us detecting method. Finally observation event infrared band increase for detection exoplanets.
