tonalli: an asexual genetic code to characterise APOGEE-2 stellar spectra. I. Validation with synthetic and solar spectra
Lucía 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 rotationa…
HIP 8522: A Puzzling Young Solar Twin with the Lowest Detected Lithium
Jhon Yana Galarza, Diego Lorenzo-Oliveira, Thiago Ferreira +8
We present HIP 8522, a young solar twin with the lowest detected lithium, potentially a field blue straggler or the result of episodic early accretion. Its stellar parameters ($T_{…
Atmospheric parameters and chemical abundances within 100 pc. A sample of G, K, and M main-sequence stars
Ricardo López-Valdivia, Lucía Adame, Eduardo Zagala Lagunas +9
To date, we have access to enormous inventories of stellar spectra that allow the extraction of atmospheric parameters and chemical abundances essential in stellar studies. However…
Rotational Evolution of Classical T Tauri Stars: Models and Observations
Javier Serna, Giovanni Pinzón, Jesús Hernández +17
We developed a grid of stellar rotation models for low-mass and solar-type Classical T Tauri stars (CTTS) (). These models incorporate the star-…
ABYSS II: Identification of young stars in optical SDSS spectra and their properties
Serat Saad, Kaitlyn Lane, Marina Kounkel +9
We developed a tool that measures equivalent widths of various lines in low resolution optical spectra, and it was applied to stellar spectra obtained as part of SDSS-V and LAMOST…
