Starspots and active regions on the chromospherically active binary MS Ser
The quasisimultaneous electrophotometric, polarimetric and spectroscopicobservations of the chromospherically active binary MS Ser arepresented. The photometric variability of the star can be describedcompletely by a zonal spottedness model. Spotted regions occupy up to21% of the total stellar surface. The temperature difference between theunspotted photosphere and starspots is about 1300 K. Starspots arelocalized at the middle latitudes. We detected the broad-band linearpolarization of the stellar light and its rotational modulationconnected with the local magnetic region on the stellar surface. Wesuspect that there is a space connection between plages, magneticregions and the mostly spotted stellar longitudes.
