Massive stars in the SDSS-V survey: New O2 stars in the Large Magellanic Cloud

A. Roman-Lopes, J. G. Fernández-Trincado, Marina Kounkel +7

{O2 stars define the hottest end of the normal O-star sequence, but their identification requires blue-optical nitrogen diagnostics absent from many surveys.} {We reassess three lu…

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…

SDSS-V Local Volume Mapper (LVM): The Integrated Light and Internal Rotation of Omega Centauri

Maximilian Häberle, Dmitry Bizyaev, Alina Boecker +34

The SDSS-V Local Volume Mapper (LVM) is a wide-field integral field spectroscopic survey of the Southern Milky Way plane, the Magellanic Clouds, and nearby Local Group galaxies. We…

A Probabilistic Framework for Population Studies of the Solar Neighborhood: Application to SDSS-V and Gaia

Ilija Medan, Keivan G. Stassun, Zachary Way +8

Studies of the Solar Neighborhood require spectroscopic follow-up of stars identified in astrometric surveys to fully characterize their physical properties. The SDSS-V Solar Neigh…

Pre-main Sequence B Stars Surrounding the Orion Nebula

P. H. F. B. Braz, A. Roman-Lopes, W. J. B. Corradi +6

Pre-main sequence (PMS) early-type stars are rare due to their rapid evolution. Confirming PMS B stars is accordingly valuable for constraining higher mass star formation scenarios…
