Effective temperatures and bolometric corrections for some galactic Wolf-Rayet stars from absolute spectrophotometry.
Abstract
The author presents the absolute continuum fluxes of Wolf-Rayet stars measured in the region λλ3100 - 8090 Å by a two channel scanner built up cooperatively by the Observatoire of Lyon and the Laboratoire d'Astronomie Spatiale (L.A.S.). The dereddened fluxes together with IUE and ANS ultraviolet data are compared to those of Kurucz's LTE model atmospheres in order to derive effective temperatures and bolometric corrections. The resulting effective temperatures and bolometric corrections for these stars are found to range from 25,000 to 32,700K, and from B.C. = -2.5 to -3.7 mag. respectively.
