Abstract

To investigate the star spots of the M dwarf GJ 1214, we conducted a multi-color photometric monitoring from 2012 to 2016. We measured the rotation period of the host star, measured an increase in variability amplitude, determined the permanent spot filling factor, the spot temperature contrast and persistent longitudes. We determined the effect of the star spots on the planetary transmission spectrum.
