The evidence is reviewed that Population I Wolf-Rayet stars have solar abundances, that they are surrounded by remnant disks formed from their natal clouds, and that their rate of mass loss is moderate. These properties are consistent with Wolf-Rayet

The physical state of the mantle of a star (its chromosphere, corona, and wind) is chiefly determined by the amount of nonradiative heat and momentum deposited in the mantle. Because the presence of magnetic lines of force buffeted by turbulent or co

I first met Edith Muller in connection with my studies of the theories and observations of the spectra of massive stars and her related studies of the spectrum of the Sun. Later I was well aware of her work as General Secretary of the International A

New orbital elements for the 112.4 day WN4.5+09.5Ia spectroscopic binary HD 190918 are presented. Solutions consistent with the O star being a main sequence star or a supergiant are obtained when i = 25° or 20°, respectively. We predict the X-ray f

The fundamental properties of the Wolf-Rayet components of V444 Cygni and CQ Cephei such as mass, effective temperature, and luminosity are presented. These properties are consistent with these stars being young objects recently arrived on the main s

Maeder uses three criteria to define the Wolf-Rayet stage of stellar evolution, namely (1) anomalous surface abundances like those in nuclear processed material, (2) an effective temperature higher than 30,000 K, and (3) a dense wind with a rate of m
