Estimating stellar fundamental parameters using PCA: application to early type stars of GES data

W. Farah, M. Gebran, F. Paletou et R. Blomme

Résumé

This work addresses a procedure to estimate fundamental stellar parameters such as T eff , logg, [Fe/H], and v sin i using a dimensionality reduction technique called Principal Component Analysis (PCA), applied to a large database of synthetic spectra. This technique shows promising results for inverting stellar parameters of observed targets from Gaia ESO Survey.
