ABYSS. IV. Identifying signatures of stellar youth in APOGEE spectra
Valentina Bonilla Villalobos, Marina Kounkel, Joseph Mullen +9
We develop a convolutional neural network classifier that performs spectroscopic identification of stellar youth (<40 Myr) in APOGEE spectra. This classifier is sensitive to severa…
Effective temperatures estimation of low-mass stars and identification of T Tauri stars in LAMOST DR10 using machine learning
C. D. Millan-Valderrama, J. Hernandez, B. Sabogal +1
We present effective temperature (Teff) estimates of low-mass stars and T Tauri stars (TTS) candidate detections derived from automated spectroscopic measurements and low-complexit…
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…
Measurement of the angular momenta of pre-main-sequence stars: early evolution of slow and fast rotators and empirical constraints on spin-down torque mechanisms
Marina Kounkel, Keivan G. Stassun, Lynne A. Hillenbrand +3
We use TESS full-frame imaging data to investigate the angular momentum evolution of young stars in Orion Complex. We confirm recent findings that stars with rotation periods faste…
Structure and kinematics of the Taurus star-forming region from Gaia-DR2 and VLBI astrometry
P. A. B. Galli, L. Loinard, H. Bouy +9
Aims:We take advantage of the second data release of the Gaia space mission and the state-of-the-art astrometry delivered from very long baseline interferometry observations to rev…
