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…

Looking for Companionship: Radial Velocity Follow-Up of Lithium-Rich Giants with ESPRESSO

Maryum Sayeed, Andrew R. Casey, Benjamin T. Montet +4

Lithium-rich red giants have been a long-standing mystery in stellar astrophysics. A leading theory to explain these chemically peculiar and rare objects is interactions with a clo…

The Nineteenth Data Release of the Sloan Digital Sky Survey

SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210

Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…

Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy

Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217

The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…

SDSS-V Milky Way Mapper (MWM): ASPCAP Stellar Parameters and Abundances in SDSS-V Data Release 19

Szabolcs Mészáros, Paula Jofré, Jennifer A. Johnson +25

The goal of this paper is to describe the science verification of Milky Way Mapper (MWM) APOGEE Stellar Parameter and Chemical Abundances Pipeline (ASPCAP) data products published…

Probing Binary Architectures of Lithium-Rich Giants in GALAH with COSMIC and Stellar Models

Maryum Sayeed, Selina Yang, Giulia Cinquegrana +5

Surface lithium is depleted when a star goes through the first dredge-up phase, yet of red giants are found to be Li-rich. The formation mechanism for these remains uncertain…

Metallicity fluctuation statistics in the interstellar medium and young stars -- II. Elemental cross-correlations and the structure of chemical abundance space

Mark R. Krumholz, Yuan-Sen Ting, Zefeng Li +3

Observations of Milky Way stars by multiplexed spectroscopic instruments and of gas in nearby galaxies using integral field units have made it possible to measure the abundances of…

A Data-Driven M Dwarf Model and Detailed Abundances for 17,000 M Dwarfs in SDSS-V

Aida Behmard, Melissa K. Ness, Andrew R. Casey +6

The cool temperatures of M dwarf atmospheres enable complex molecular chemistry, making robust characterization of M dwarf compositions a long-standing challenge. Recent modificati…

The Multiband Imaging Survey for High-Alpha PlanetS (MISHAPS) I: Preliminary Constraints on the Occurrence Rate of Hot Jupiters in 47 Tucanae

Alison L. Crisp, Jonas Klüter, Marz L. Newman +14

The first generation of transiting planet searches in globular clusters yielded no detections, and in hindsight, only placed occurrence rate limits slightly higher than the measure…

Strong Chemical Tagging in FIRE: Intra and Inter-Cluster Chemical Homogeneity in Open Clusters in Milky Way-like Galaxy Simulations

Binod Bhattarai, Sarah R. Loebman, Melissa K. Ness +4

Open star clusters are the essential building blocks of the Galactic disk; "strong chemical tagging" - the premise that all star clusters can be reconstructed given chemistry infor…

In the Galactic disk, stellar [Fe/H] and age predict orbits and precise [X/Fe]

Melissa K. Ness, Kathryn V. Johnston, Kirsten Blancato +4

We explore the structure of the element abundance--age--orbit distribution of the stars in the Milky Way's low- disk, by (re-)deriving precise [Fe/H], [X/Fe] and ages, along wit…
