CCD-BASED SPECTROSCOPY OF WOLF-RAYET STARS: STUDY OF EXPANSION VELOCITY AND MASS LOSS AS A CONTRIBUTOR IN INTERSTELLAR MATTER ENRICHMENT
Wolf-Rayet stars was discovered by C.Wolf and G.Rayet in 1867. In the spectra of Wolf-Rayet stars, broad emission lines caused by Doppler broadening can be observed. This indicate that Wolf-Rayet stars have high expansion velocity. It is also known that Wolf-Rayet stars have high mass loss rates com...
