Variation of Radiation in Pleione During Shell and Be Phases

Abstract

The analysis of the spectrophotometric observations of Pleione, a wonderful object in Pleiades cluster, has been carried out in the wavelength range of 3200-5500 Å. The amount of emitted radiation at Balmer continuum and Balmer jump has been measured in term of magnitudes. Our present measurements have been combined with the earlier measurements to investigate the relation between the variation of the emitted radiation and phase changes in Pleione.
