| Abstract: |
A transiting planet acts as a sharply defined shutter that scans the surface of
its host star.
Based on very-low-noise photometry from the CoRoT satellite and high-resolution
spectra taken with VLT/UVES we employ this shutter to resolve
surface features of the highly active G-type star CoRoT-2a which is transited
by the planet CoRoT-2b. We shortly discuss the age of the CoRoT-2 system based on
the equivalent width of the Li I λ 6708 Å line
of 140 ± 1 mÅ. |
