Résumé
Nous présentons une mise à jour de la grille des modèles d’atmosphère détaillés et des spectres synthétiques homogénes pour les étoiles sous-naines chaudes de haute gravité. Les spectres haute résolution et la photométrie synthétique ont été calculés dans la gamme de longueurs d’onde 1.000 Å - 10.000 Å à l’aide de structures atmosphériques non-LTE entiérement recouvertes de lignes.
Mots-clés : spectres synthétiques, atmosphères stellaires, profils de ligne, sous-naines
Abstract
We present an update of the grid of detailed atmosphere models and homogeneous synthetic spectra for hot, high-gravity subdwarf stars. High-resolution spectra and synthetic photometry were calculated in the wavelength range 1,000 Å – 10,000 Å using Non-LTE extensively line-blanketed atmosphere structures.
Keywords : synthetic spectra, stellar atmospheres, line profiles, subdwarfs
