Regardless of the degree of elaboration of series of models, just how can they be used for calibration purposes? And how much is this calibration sensitive to the quality of the model theory? These two questions are the basis of our discussion, which covers : I – The general principles of the use of model atmospheres in stellar calibration (1 – The two dimensional classifications; 2 – The use of the total luminosity; 3 – The cases of Vega and Sirius; 4 – The calibration of ST – Teff relation); II – The failures of the two parameters model atmospheres (1 – The observational need for more-than-two-parameters classification; 2 – The abundance of elements, the line formation, and the model atmospheres; 3 – Various sources of unadequacy of models; 4 – Envelopes or shell features; their influence on model-building; 5 – The case of HD 45677. Diagnostic of early-type stars; 6 – Various unexplained spectral features); III – The present state of the model factory (1 – The classical models; 2 – New concepts in the description of a stellar atmosphere; 3 – New approaches in model making; 4 – Conclusions).

Résumé

Résumé

Indépendamment du degré d'élaboration des réseaux de modèles, comment peut-on s'en servir pour la calibration des spectres? Et à quel degré une telle calibration est-elle sensible à la qualité des modèles utilisés?

Ces deux questions forment la base de notre discussion, qui couvre les points suivants : I – Principes généraux de l'utilisation des modèles d'atmosphère dans la calibration stellaire (1 – Les classifications à deux dimensions; 2 – L'utilisation de la luminosité totale; 3 – Le cas de Véga et Sirius; 4 – La calibration de la relation TS – Teff; II – Les échecs des classifications utilisant des modèles à 2 paramètres (1 – Le besoin observationnel pour une classification à plus de deux paramètres; 2 – L'abondance des éléments, la formation des raies, et les modèles; 3 – Différentes sources d'inadaptation des modèles à la réalité; 4 – Caractéristiques d'enveloppes ou de couches; leur influence sur la construction des modèles; 5 – Le cas de HD 45677; le diagnostic des étoiles chaudes; 6 – Diverses observations spectroscopiques non expliquées); III – L'état actuel de l'usine à modèles (1 – Les modèles classiques; 2 – Nouveaux concepts dans la description d'une atmosphère stellaire; 3 – Nouvelles approches en vue de la construction des modèles; 4 – Conclusions).
