Scientific paper

The relationship between Mg ¥± emission line and light variation of V711 Tau has been derived to investigate the chromospheric activity on V711 Tau. First, a shape of an optical light curve was compared with that of ultraviolet constructed from the IUE low resolution spectra. Second, the intensities of Mg ¥± k emission lines have been reduced from IUE high resolution spectra. The intensity of Mg ¥± k line was compared with brightness of the UV light curve at given phase. The Mg ¥± line intensity is maximum at the phase 0.p4 where the light is minimum. The evidence of chromosperic activity is indicated by the intensity variation of the Mg ¥± emission line with orbital phase for V711 Tau.
