Using autoencoders and deep transfer learning to determine the stellar parameters of 286 CARMENES M dwarfs

no code implementations • 14 May 2024 • P. Mas-Buitrago, A. González-Marcos, E. Solano, V. M. Passegger, M. Cortés-Contreras, J. Ordieres-Meré, A. Bello-García, J. A. Caballero, A. Schweitzer, H. M. Tabernero, D. Montes, C. Cifuentes

Our results are broadly consistent with those of recent studies using CARMENES data, with a systematic deviation in our Teff scale towards hotter values for estimations above 3750 K. Furthermore, our methodology mitigates the deviations in metallicity found in previous DL techniques due to the synthetic gap.

StePar: an automatic code to infer stellar atmospheric parameters

1 code implementation • 15 Jul 2019 • H. M. Tabernero, E. Marfil, D. Montes, J. I. González Hernández

Context: StePar is an automatic code written in Python 3. X designed to compute the stellar atmospheric parameters Teff, log(g), [Fe/H], and of FGK-type stars by means of the EW method.
