Sliced Inverse Regression: application to fundamental stellar parameters
S. Kassounian, M. Gebran, F. Paletou +1
We present a method for deriving stellar fundamental parameters. It is based on a regularized sliced inverse regression (RSIR). We first tested it on noisy synthetic spectra of A,…
Inference of an explanatory variable from observations in a high-dimensional space: application to high-resolution spectra of stars
V. Watson, JF. Trouilhet, F. Paletou +1
Our aim is to evaluate fundamental parameters from the analysis of the electromagnetic spectra of stars. We may use - spectra; each spectrum being a vector with -…
A new method for the inversion of atmospheric parameters of A/Am stars
M. Gebran, W. Farah, F. Paletou +2
We present an automated procedure that derives simultaneously the effective temperature , the surface gravity logg, the metallicity [Fe/H], and the equatorial projected ro…
Principal component analysis-based inversion of effective temperatures for late-type stars
F. Paletou, M. Gebran, E. R. Houdebine +1
We show how the range of application of the principal component analysis-based inversion method of Paletou et al. (2015) can be extended to late-type stars data. Besides being an e…
Inversion of stellar fundamental parameters from Espadons and Narval high-resolution spectra
F. Paletou, T. Böhm, V. Watson +1
The general context of this study is the inversion of stellar fundamental parameters from high-resolution Echelle spectra. We aim indeed at developing a fast and reliable tool for…
