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…
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…
Spectroscopic Follow-up of Young High- Dwarf Star Candidates: Still Likely Genuinely Young
Yuxi Lu, Catherine Manea, Maryum Sayeed +9
The question of whether genuinely young high- stars exist has been discussed for over a decade since their discovery from asteroseismology of giant stars as it is challenging t…
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…
Exoplanet Occurrence Rate with Age for FGK Stars in Kepler
Maryum Sayeed, Ruth Angus, Travis Berger +5
We measure exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1-17 DR25 Kepler data. We employ Kepler…
