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…
Argon Abundances in the Solar Neighborhood: Non-LTE Analysis of Orion Association B-type Stars
Thierry Lanz, Katia Cunha, Jon Holtzman +1
Argon abundances have been derived for a sample of B main-sequence stars in the Orion association. The abundance calculations are based on NLTE metal line-blanketed model atmospher…
A Mid-Infrared Spitzer Study of the Herbig Be Star R Mon and the Associated HH 39 Herbig-Haro Object
M. Audard, S. Skinner, M. Guedel +3
We report on initial results of our Spitzer Cycle 2 program to observe the young massive star R Mon and its associated HH 39 Herbig-Haro object in the mid-infrared. Our program use…
Modeling multidimensional effects in the propagation of radiative shocks
Sébastien Leygnac, Laurent Boireau, Claire Michaut +4
Radiative shocks (also called supercritical shocks) are high Mach number shock waves that photoionize the medium ahead of the shock front and give rise to a radiative precursor. Th…
A Grid of NLTE Line-Blanketed Model Atmospheres of Early B-type Stars
Thierry Lanz, Ivan Hubeny
We have constructed a comprehensive grid of 1540 metal line-blanketed, NLTE, plane-parallel, hydrostatic model atmospheres for the basic parameters appropriate to early B-type star…
A New Formation Mechanism for the Hottest Horizontal-Branch Stars
Allen V. Sweigart, Thomas M. Brown, Thierry Lanz +2
Stars with very large mass loss on the red-giant branch can undergo the helium flash while descending the white-dwarf cooling curve. Under these conditions the flash convection zon…
