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…

Elemental abundances of 44 very metal-poor stars determined from Subaru/IRD near-infrared spectra

Wako Aoki, Timothy C. Beers, Satoshi Honda +12

Abundances of five elements, Na, Mg, Al, Si, and Sr, are investigated for 44 very metal-poor stars (-4.0 < [Fe/H] < -1.5) in the Galactic halo system based on an Local Thermodinami…

Spatially Resolved Stellar Populations of Galaxies in WHL0137-08 and MACS0647+70 Clusters as Revealed by JWST: How do Galaxies Grow and Quench Over Cosmic Time?

Abdurro'uf, Dan Coe, Intae Jung +20

We study the spatially resolved stellar populations of 444 galaxies at in two clusters (WHL0137-08 and MACS0647+70) and a blank field, combining imaging data from HST a…

JWST Imaging of Earendel, the Extremely Magnified Star at Redshift

Brian Welch, Dan Coe, Erik Zackrisson +60

The gravitationally lensed star WHL0137-LS, nicknamed Earendel, was identified with a photometric redshift based on images taken with the Hubble Space Tele…

Carbon-Enhanced Metal-Poor star candidates from BP/RP Spectra in DR3

Madeline Lucey, Nariman Al Kharusi, Keith Hawkins +6

Carbon-enhanced metal-poor (CEMP) stars comprise almost a third of stars with [Fe/H] < --2, although their origins are still poorly understood. It is highly likely that one sub-cla…

On the inconsistency of [C/Fe] abundances and the fractions of carbon-enhanced metal-poor stars among various stellar surveys

Anke Arentsen, Vinicius M. Placco, Young Sun Lee +4

Carbon-enhanced metal-poor (CEMP) stars are a unique resource for Galactic archaeology because they probe the properties of the First Stars, early chemical evolution and binary int…

The role of binaries in the enrichment of the early Galactic halo. III. Carbon-enhanced metal-poor stars -- CEMP-s stars

T. T. Hansen, J. Andersen, B. Nordström +4

Detailed spectroscopic studies of metal-poor halo stars have highlighted the important role of carbon-enhanced metal-poor (CEMP) stars in understanding the early production and eje…

The role of binaries in the enrichment of the early Galactic halo. II. Carbon-Enhanced Metal-Poor Stars - CEMP-no stars

T. T. Hansen, J. Andersen, B. Nordström +4

The detailed composition of most metal-poor halo stars has been found to be very uniform. However, a fraction of 20-70% (increasing with decreasing metallicity) exhibit dramatic en…

The role of binaries in the enrichment of the early Galactic halo. I. r-process-enhanced metal-poor stars

T. T. Hansen, J. Andersen, B. Nordstrøm +3

The detailed chemical composition of most metal-poor halo stars has been found to be highly uniform, but a minority of stars exhibit dramatic enhancements in their abundances of he…
