Atmospheric parameters and chemical abundances of young stars with APOGEE. I. Orion star-forming region
Ricardo López-Valdivia, LucÃa Adame, Carlos G. Román-Zúñiga +19
We derive atmospheric parameters and chemical abundances in young G-, K-, and M-type stars (temperatures between 6500 and 3100 K) using infrared APOGEE-2 spectra. Atmospheric param…

tonalli: an asexual genetic code to characterise APOGEE-2 stellar spectra. I. Validation with synthetic and solar spectra
LucÃa Adame, Carlos Román-Zúñiga, Jesús Hernández +2
We present tonalli, a spectroscopic analysis python code that efficiently predicts effective temperature, stellar surface gravity, metallicity, -element abundance, and rotation…
