Theories explaining the continual expansion of the outer atmospheric layers of luminous
early-and late-type stars are reviewed. The radiative, coronal, and hybrid stellar-wind theories …

This long-awaited graduate textbook, written by two pioneers in the field, provides a
comprehensive introduction to the observations, theories, and consequences of stellar winds. The …

The preliminary results of the Einstein Observatory stellar X-ray survey are presented. To
date, 143 soft X-ray sources have been identified with stellar counterparts, leaving no doubt …

Equatorial disk formation around rotating stars due to Ram pressure confinement ADS Classic
is now deprecated. It will be completely retired in October 2019. This page will automatically …

Despite extensive study, the mechanisms by which Be star disks acquire high densities and
angular momentum while displaying variability on many timescales are still far from clear. In …

Conditions for the formation of massive stars ADS Classic is now deprecated. It will be
completely retired in October 2019. This page will automatically redirect to the new ADS interface …

The spectra are at a higher energy resolution than earlier X-ray observations of OB supergiants,
and this allows stronger constraints to be placed on the location of the emission source …

R136 (HD 38268) is the central object of the 30 Doradus Nebula, a giant region of ionized
hydrogen in the Large Magellanic Cloud. Observations of R136 at low and high spectral …

We present results from an investigation of the dynamical behavior of buoyant magnetic flux
rings in the radiative interior of a uniformly rotating, early-type star. Our physical model …

The ROSAT all-sky survey has been used to study the X-ray properties for all OB-type stars
listed in the Yale Bright Star Catalogue. Here we present a detailed astrophysical discussion …
