Mon-250. a) 2011 CoRoT light curve folded in phase. b) Hα line profile during different rotational phases, indicated in each panel. A redshifted absorption component seen only near phase 0.5 is indicated by a red arrow. c) Measured veiling folded in phase. d) Shift in radial velocity measured from photospheric lines in the spectra, folded in phase. In all four panels, the same period of 8.6 days, determined from the radial velocity variation of photospheric lines, was used to calculate the phase. The same initial date was also used.
