Emission-line Stars and Early-type Stars with Gaia [PDF]

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 [PDF]

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.
