SDSS-IV MaStar: Determination of Stellar Parameters Using Bayesian Averaging
Yan-Ping Chen, Renbin Yan, Szabolcs Mészáros +12
We present the stellar parameters for 59,266 high-quality spectra of 24,130 unique stars from the MaNGA Stellar Library (MaStar) in the Sloan Digital Sky Survey (SDSS) Data Release…
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…
The Impact of the MAST Data Archive
Richard A. Shaw, Jenny L. Novacescu, Sarah Weissman +31
The Barbara A. Mikulski Archive for Space Telescopes (MAST) hosts science-ready data products from over twenty NASA missions, plus community-contributed data collections, and other…
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…
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…
StarFlow: Leveraging Normalizing Flows for Stellar Age Estimation in SDSS-V DR19
Alexander Stone-Martinez, Jon A. Holtzman, Yuxi +6
Understanding the ages of stars is crucial for unraveling the formation history and evolution of our Galaxy. Traditional methods for estimating stellar ages from spectroscopic data…
The size of the Milky Way galaxy
Jianhui Lian, Gail Zasowski, Bingqiu Chen +4
The size of a galaxy is one of the fundamental parameters that reflects its growth and assembly history. Traditionally, the size of the Milky Way has been characterized by the scal…
A Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
Julie Imig, Cathryn Price, Jon A. Holtzman +24
We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), -element abundances ([Mg/Fe]), and stellar age, using a sample of 66,496 red giant st…
The Chemodynamics of the Stellar Populations in M31 from APOGEE Integrated Light Spectroscopy
Benjamin J. Gibson, Gail Zasowski, Anil Seth +8
We present analysis of nearly 1,000 near-infrared, integrated light spectra from APOGEE in the inner 7 kpc of M31. We utilize full spectrum fitting with A-LIST simple stellar…
SDSS-IV MaStar: Stellar Parameter Determination with Continuum-Supplemented Full-Spectrum Fitting
Daniel Lazarz, Renbin Yan, Ronald Wilhelm +13
We present a stellar parameter catalog built to accompany the MaStar Stellar Library, which is a comprehensive collection of empirical, medium-resolution stellar spectra. We constr…
The Milky Way tomography with APOGEE: intrinsic density distribution and structure of mono-abundance populations
Jianhui Lian, Gail Zasowski, Ted Mackereth +11
The spatial distribution of mono-abundance populations (MAPs, selected in [Fe/H] and [Mg/Fe]) reflect the chemical and structural evolution in a galaxy and impose strong constraint…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
SDSS-IV MaStar: Data-driven Parameter Derivation for the MaStar Stellar Library
Julie Imig, Jon A. Holtzman, Renbin Yan +10
The MaNGA Stellar Library (MaStar) is a large collection of high-quality empirical stellar spectra designed to cover all spectral types and ideal for use in the stellar population…
SDSS-IV MaStar: Theoretical Atmospheric Parameters for the MaNGA Stellar Library
Lewis Hill, Daniel Thomas, Claudia Maraston +16
We calculate the fundamental stellar parameters effective temperature, surface gravity and iron abundance - T, log g, [Fe/H] - for the final release of the Mapping Near…
A Multi-Year Search For Transits Of Proxima Centauri. II: No Evidence For Transit Events With Periods Between 1-30 Days
Dax L. Feliz, David L. Blank, Karen A. Collins +13
Using a global network of small telescopes, we have obtained light curves of Proxima Centauri at 329 observation epochs from 2006 - 2017. The planet Proxima b discovered by Anglada…
SDSS-IV MaStar -- A Large and Comprehensive Empirical Stellar Spectral Library: First Release
