Magnetic Activity and Possible Anti-solar Differential Rotation in Two RS CVn–type Eclipsing Binaries
Using Kepler photometry and LAMOST spectroscopy, we present the first combined photometric and spectroscopic investigations for two Kepler eclipsing binaries: KIC 8893936 and KIC 10014830. Precise absolute physical parameters are derived from simultaneous modelling of light curves and radial-velocity curves. Evolutio...
