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…
Data Release 2 of S-PLUS: accurate template-fitting based photometry covering 1000 square degrees in 12 optical filters
F. Almeida-Fernandes, L. Sampedro, F. R. Herpich +26
The Southern Photometric Local Universe Survey (S-PLUS) is an ongoing survey of 9300 deg in the southern sky in a 12-band photometric system. This paper presents the seco…
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…
Targeting Bright Metal-poor Stars in the Disk and Halo Systems of the Galaxy
Guilherme Limberg, Rafael M. Santucci, Silvia Rossi +7
We present the results of spectroscopic follow-up for 1897 low-metallicity star candidates, selected from the Best & Brightest (B&B) Survey, carried out with the GMOS-N/S (Gemini N…
