Optical spectroscopy of an m-type star / Arrief Azzahir Daud

In this research, the researcher performs the astronomical spectroscopy of an M-type star aided by 20 inch telescope, CCD and spectrograph. The researcher were successfully obtained absorption lines spectrum of the M-type star (Betelgeuse) at 3 different ranges and exposure time. Analysis of the M-t...
