Rotational periods and evolutionary models for subgiant stars observed by CoRoT
J. -D. Jr. do Nascimento, J. S. da Costa, M. Castro
We present rotation period measurements for subgiants observed by CoRoT. Interpreting the modulation of stellar light that is caused by star-spots on the time scale of the rotation…
