The spectroscopic observations of CoRoT asteroseismic targets with HARPS

Ennio Poretti, Monica Rainer, Luciano Mantegazza +6

CoRoT photometric measurements of asteroseismic targets need complementary ground-based spectroscopic observations. We are using the planet-hunter HARPS spectrograph attached to th…

Photometric variability of the Be star CoRoT-ID 102761769

M. Emilio, L. Andrade, E. Janot-Pacheco +16

Classical Be stars are rapid rotators of spectral type late O to early A and luminosity class V-III, wich exhibit Balmer emission lines and often a near infrared excess originating…

Pulsations in the late-type Be star HD 50209 detected by CoRoT

P. D. Diago, J. Gutierrez-Soto, M. Auvergne +22

The presence of pulsations in late-type Be stars is still a matter of controversy. It constitutes an important issue to establish the relationship between non-radial pulsations and…

Early-type PMS and MS objects in M16 and the Carina star-forming regions

Christophe Martayan, Michele Floquet, Yves Fremat +4

Thanks to a variety of pertinent wide-angle facilities (WFI-slitless mode, VLT-FLAMES (Pasquini et al. 2002), SPITZER, 2MASS) it is possible to comprehensively study the nature of…

The Gaia satellite: a tool for Emission Line Stars and Hot Stars

Christophe Martayan, Yves Fremat, Ronny Blomme +19

The Gaia satellite will be launched at the end of 2011. It will observe at least 1 billion stars, and among them several million emission line stars and hot stars. Gaia will provid…

Radial velocities, dynamics of stars and nebulosities with GAIA and VLT-GIRAFFE

Christophe Martayan, Yves Fremat, Ronny Blomme +8

This document is divided in two parts. The first part deals with the radial velocities (RV) distributions for B-type stars and nebulosities observed with the VLT-GIRAFFE in the Lar…
