Wolf-Rayet star
A Wolf-Rayet star is a rare, massive, and extremely hot star characterized by strong stellar winds and significant mass loss. These stars are in a late stage of stellar evolution, often preceding a supernova explosion, and are known for their broad emission lines of ionized elements in their spectra.
