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…
Spectral Disentangling Reveals Deep CNO-cycle Exposure in ET Cru
Gökhan Yücel, Volkan Bakış, Christian Nitschelm +2
Binary stars undergoing mass transfer provide unique laboratories for testing stellar evolution. Here, we present a comprehensive photometric and spectroscopic analysis of the semi…
A Galactic Self-Portrait: Density Structure and Integrated Properties of the Milky Way Disk
Julie Imig, Jon A. Holtzman, Gail Zasowski +23
The evolution history of the Milky Way disk is imprinted in the ages, positions, and chemical compositions of individual stars. In this study, we derive the intrinsic density distr…
Abundances of P, S, and K in 58 bulge spheroid stars from APOGEE
B. Barbuy, H. Ernandes, A. C. S. Friaça +25
We have previously studied several elements in 58 selected bulge spheroid stars, based on spectral lines in the H-band. We now derive the abundances of the less-studied elements ph…
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…
Abundances of iron-peak elements in 58 bulge spheroid stars from APOGEE
B. Barbuy, A. C. S. Friaça, H. Ernandes +22
Stars presently identified in the bulge spheroid are probably very old, and their abundances can be interpreted as due to the fast chemical enrichment of the early Galactic bulge.…
Rotational Evolution of Classical T Tauri Stars: Models and Observations
Javier Serna, Giovanni Pinzón, Jesús Hernández +17
We developed a grid of stellar rotation models for low-mass and solar-type Classical T Tauri stars (CTTS) (). These models incorporate the star-…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. III. Abundance Gradients of the Small Magellanic Cloud
Joshua T. Povick, David L. Nidever, Pol Massana +10
We determine radial- and age-abundance gradients of the Small Magellanic Cloud (SMC) using spectra of 2,062 red giant branch (RGB) field stars observed by SDSS-IV / APOGEE-2S. With…
Exploring the Origin of the Distance Bimodality of Stars in the Periphery of the Small Magellanic Cloud with APOGEE and Gaia
Andres Almeida, Steven R. Majewski, David L. Nidever +12
The Magellanic Cloud system represents a unique laboratory for study of both interacting dwarf galaxies and the ongoing process of the formation of the Milky Way and its halo. We f…
An Investigation of Non-Canonical Mixing in Red Giant Stars Using APOGEE 12C/13C Ratios Observed in Open Cluster Stars
Caroline McCormick, Steven R. Majewski, Verne V. Smith +9
Standard stellar evolution theory poorly predicts the surface abundances of chemical species in low-mass, red giant branch (RGB) stars. Observations show an enhancement of p-p chai…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. I. Calculating Individual Stellar Ages of RGB Stars in the Large Magellanic Cloud
Joshua T. Povick, David L. Nidever, Pol Massana +12
Stellar ages are critical for understanding the temporal evolution of a galaxy. We calculate the ages of over 6000 red giant branch stars in the Large Magellanic Cloud (LMC) observ…
Unveiling the time evolution of chemical abundances across the Milky Way disk with APOGEE
Bridget Ratcliffe, Ivan Minchev, Friedrich Anders +12
Chemical abundances are an essential tool in untangling the Milky Way's enrichment history. However, the evolution of the interstellar medium abundance gradient with cosmic time is…
Chemo-Dynamical Tagging in the Outskirts: The Origins of Stellar Substructures in the Magellanic Clouds
César Muñoz, Antonela Monachesi, David L. Nidever +12
We present the first detailed chemical analysis from APOGEE-2S observations of stars in six regions of recently discovered substructures in the outskirts of the Magellanic Clouds e…
StarHorse results for spectroscopic surveys + Gaia DR3: Chrono-chemical populations in the solar vicinity, the genuine thick disk, and young-alpha rich stars
Anna B. A. Queiroz, Friedrich Anders, Cristina Chiappini +16
The Gaia mission has provided an invaluable wealth of astrometric data for more than a billion stars in our Galaxy. The synergy between Gaia astrometry, photometry, and spectroscop…
