Estimation de paramètres physiques à partir de leur représentation par une base de mesures de très grande dimension

Abstract : This thesis contributes to the development of various methods for the determination of the stellar fundamental parameters (effective temperature, surface gravity and "metallicity" ie, the overall chemical composition), as well as the projected rotation speed (vsini), from the analysis of high resolution spectra. Several methods will be presented, and their respective performances in terms of extraction of the fundamental parameters will be discussed. In particular, we will focus on an original implementation of the Sliced Inverse Regression method (SIR, Watson et al., 2017).
