Expanding envelopes of early-type stars: current status.
Abstract
There are currently four theoretical models that have been developed to explain the winds or the origin of the anomalous ionization in the winds of early-type stars. This paper reports the results of a workshop on stellar winds that was held at JILA in Boulder, Colorado 1977 October 3 to 6. Subsequent work that answered some of the questions raised at the meeting is also presented. The conferees concluded that the winds are probably due to radiation pressure in ultraviolet resonance lines, but that the anomalously high degree of ionization in the winds require the input of nonthermal energy. Several as yet unexplained observations are mentioned and areas for future studies are outlined.
