Spectral characterization and differential rotation study of active CoRoT stars

Nagel, Evangelos, Czesla, Stefan, Schmitt, Jürgen H. M. M.

Understand

The CoRoT space telescope observed nearly 160 000 light curves.

Among the most outstanding is that of the young, active planet host star CoRoT-2A.
In addition to deep planetary transits, the light curve of CoRoT-2A shows strong rotational variability and a superimposed beating pattern.
To study the stars that produce such an intriguing pattern of photometric variability, we identified a sample of eight stars with rotation periods between 0.8 and 11 days and photometric variability amplitudes of up to 7.5 %, showing a similar CoRoT light curve.
