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
The paper describes the twentieth data release (DR20) of the Sloan Digital Sky Survey, providing over 3 million new optical spectra from the SDSS‑V Milky Way, Black Hole, and Local…
The Open Cluster Chemical Abundances and Mapping Survey: IX. Measuring the Effects of Stellar Diffusion in the Open Clusters NGC 752 and Ruprecht 147 using APOGEE
Diogo Souto, Taylor Spoo, Peter M. Frinchaboy +4
The study analyzes APOGEE spectroscopic data for the open clusters NGC 752 and Ruprecht 147 to detect elemental abundance differences between turnoff and cooler main‑sequence stars…
A Chemical Mismatch Between Young Stars and Their Inner Disks
Diogo Souto, Ilaria Pascucci, Katia Cunha +1
We present the first stellar elemental abundance study for two very low-mass stars, similar in mass to TRAPPIST-1, in the \,Myr-old Upper-Sco association. Their mid-infra…
The Chemical Homogeneity of Single-Lined Spectroscopic Binaries in Open Clusters
Amaya Sinha, Gail Zasowski, Natalie R. Myers +16
Using SDSS-V DR19 Milky Way Mapper APOGEE data, we measure the impact that close binarity has on surface chemistry across the Hertzsprung-Russell diagram in a broad set of abundanc…
Reconstructing the Milky Way chemical map with Galactic Chemical Evolution tool OMEGA+ from SDSS-MWM
Viola Hegedűs, Szabolcs Mészáros, Blanka Világos +4
We obtain two-infall galactic chemical evolution (GCE) models simulating the chemical evolution of the Milky Way as constrained by a golden sample of stellar abundances o…
