The WC6 Wolf-Rayet star MLA 1159 in M 31 and its ionization nebula BA1-642.
GREINER J., TOVMASSIAN G., KOMOSSA S., ROSADO M. and ARRIETA A.
Abstract (from CDS):
We report on optical imaging and spectroscopic observations of the Wolf-Rayet candidate star MLA 1159 and the surrounding ionization nebula BA1-642 in the Andromeda Galaxy. Though both objects have been known for many years, our observations (1) confirm the Wolf-Rayet nature of MLA 1159, (2) allow one to determine the nebula as an ionization nebula, and (3) demonstrate the association of MLA 1159 with the nebula. The supersoft X-ray source RXJ0045.5+4206 whose error box encompasses the full nebula, seems to be a chance superposition and not related to MLA 1159 and/or BA 1-642.
