Abstract: | Using EG & G spectrograph coupled with reticon array detector and Optical Multichannel Analyser (OMA) at the Cassegrain focus of the 104 cm telescope of the U.P. State Observatory, Naini Tal, several well known bright Be stars were observed in the visible region of the spectrum. Their effective temperatures and gravities were estimated by superposing the theoretical atmospheric modes of Kurucz (1991)over the observed energy distribution curves of the stars. The equivalent widths of the Balmer emission lines for these stars were also determined. For Pleione and gamma Cas, the change in equivalent widths with time was noted and the possible reason for this change was discussed. |
