The SDSS-Gaia View of the Color-Magnitude Relation for Blue Horizontal-branch Stars
Fabrícia O. Barbosa, Rafael M. Santucci, Silvia Rossi +3
We present an updated sample of blue horizontal-branch (BHB) stars selected from the photometric and spectroscopic data from Sloan Digital Sky Survey and its associated project Slo…
Canis Major OB1 stellar groups contents revealed by Gaia
T. Santos-Silva, H. D. Perottoni, F. Almeida-Fernandes +15
Canis Major OB1 (CMa OB1) is a Galactic stellar association with a very intriguing star-formation scenario. There are more than two dozen known star clusters in its line of sight,…
Abundance Patterns of and Neutron-capture Elements in the Helmi Stream
Guilherme Limberg, Rafael M. Santucci, Silvia Rossi +6
We identified 8 additional stars as members of the Helmi stream (HStr) in the combined GALAH+ DR3 and EDR3 catalog. By consistently reevaluating claimed members from the lit…
SPLUSJ210428.01-004934.2: An Ultra Metal-Poor Star Identified from Narrowband Photometry
Vinicius M. Placco, Ian U. Roederer, Young Sun Lee +6
We report on the discovery of SPLUS J210428.01-004934.2, an ultra metal-poor (UMP) star first identified from the narrow-band photometry of the Southern Photometric Local Universe…
Searching for Extragalactic Exoplanetary Systems: the Curious Case of BD+20 2457
Hélio D. Perottoni, João A. S. Amarante, Guilherme Limberg +4
Planets and their host stars carry a long-term memory of their origin in their chemical compositions. Thus, identifying planets formed in different environments improves our unders…
The Photometric Metallicity and Carbon Distributions of the Milky Way's Halo and Solar Neighborhood from S-PLUS Observations of SDSS Stripe 82
Devin D. Whitten, Vinicius M. Placco, Timothy C. Beers +14
We report photometric estimates of effective temperature, , metallicity, [Fe/H], carbonicity, [C/Fe], and absolute carbon abundances, , for over 700,000 st…
