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…
TESSExtractor: A web-based interactive tool for light-curve visualisation and period estimation using TESS full-frame images
Javier Serna, Jesús Hernández, Sean P. Matt +23
We present a user-friendly web application that allows users to extract, visualise, and interact with TESS light-curves (LCs) from full-frame images. The service works for any star…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
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…
ABYSS I: Targeting strategy for APOGEE & BOSS young star survey in SDSS-V
Marina Kounkel, Eleonora Zari, Kevin Covey +15
The fifth iteration of the Sloan Digital Sky Survey (SDSS-V) is set to obtain optical and near-infrared spectra of 5 million stars of all ages and masses throughout the Milky…
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…
