In the past decade, a consensus has emerged regarding the nature of classical Be stars:
They are very rapidly rotating main sequence B stars, which, through a still unknown, but …

Recent results for classical Be stars are reviewed and links to general astrophysics are
presented. Classical Be stars are B‐type stars close to the main sequence that exhibit line …

We present the results of a speckle interferometric survey of Galactic massive stars that
complements and expands upon a similar survey made over a decade ago. The speckle …

Context. About 20% of all B-type stars are classical Be stars–stars whose spectra imply the
presence of a circumstellar decretion disk. The disk phenomenon is strongly correlated with …

Massive stars play a major role in the evolution of their host galaxies and serve as important
probes of the distant Universe. It has been established that the majority of massive stars …

Rapid rotation is a fundamental characteristic of classical Be stars and a crucial property
allowing for the formation of their circumstellar disks. Past evolution in a mass and angular …

The first observations of ultraviolet spectral line profiles and intensities from the extended
solar corona (ie, more than 1.5 solar radii from Sun-center) were obtained on 13 April 1979 …

We present a set of theoretical Hα emission-line profiles of Be stars, created by
systematically varying model input parameters over a wide range of accepted values …

Be stars have generally been characterized by the emission lines in their spectra, and
especially the time variability of those spectroscopic features. They are known to also exhibit …

We report on broad multiwavelength observations of the 2010–2011 periastron passage of
the γ-ray loud binary system PSR B1259− 63. High-resolution interferometric radio …
