报告摘要： 

  ～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

Transits of extrasolar planets offer not only the possibility to study the physical properties of planets, they also provide a new possibility to diagnose the surfaces of active stars, which allows the study of surface inhomogeneities with unprecedented angular resolution.   I will discuss the modeling of extrasolar planet transit light curves, and in particular, how the analysis is affected by star spots and how the derived extrasolar planet parameters depend on the activity state of the spots.  I will specifically discuss how the transit light curves change due to the presence of star spots and how this information can be used to construct surface maps of active stars and deduce stellar properties.  I will discuss the potential of transit studies at shorter wavelengths and show how high-energy observations constrain the physical properties of extrasolar planets.
