Emission-line Stars and Early-type Stars with Gaia

open access: yesEAS Publications Series, 2010
Gaia will provide accurate parallaxes, spectrophotometry and spectroscopy for hundreds of thousands of emission-line stars across the whole HR diagram. In preparation for the Gaia mission, we are developing algorithms to recognize and classify emission-line stars. A large collection of ground-based spectroscopic observations has been collected and will

Magnetism in massive early-type stars

open access: yesEAS Publications Series, 2013
In the last five years our knowledge of magnetism in early-type stars has significantly improved because of the new gen- eration of high-resolution spectropolarimeters (ESPaDOnS@CFHT, Narval@TBL, HARPSpol@ESO). The success of the Magnetism in Massive Stars (MiMeS) Project, for example, has greatly improved our understanding of the magnetic properties ...

Isophot Observations of Early-Type Stars

Astrophysics and Space Science, 1997
Mass loss has an important effect on the evolution of early-type stars. The most reliable mass loss rates are determined from the radio continuum. However there is a wealth of observational evidence (Discrete Absorption Components, X-rays, IR continuum, Hα variability, …) indicating that the stellar wind is clumped.

Early type stars with abnormal spectra

Vistas in Astronomy, 1974
Abstract One of the areas which have received a great deal of attention in recent years is the field of the so-called early type peculiar stars. It seems that a review paper on the subject could be of some use, since it helps to visualize both the problems which have been solved and those which have not been solved or studied yet.
