Connections between Planetary Populations and the Chemical Characteristics of their Host Stars
Sol Yun, Young Sun Lee, Young Kwang Kim +3
Chemical anomalies in planet-hosting stars (PHSs) are studied in order to assess how the planetary nature and multiplicity affect the atmospheric chemical abundances of their host…
Mining S-PLUS for Metal-Poor Stars in the Milky Way
Vinicius M. Placco, Felipe Almeida-Fernandes, Anke Arentsen +4
This work presents the medium-resolution () spectroscopic follow-up of 522 low-metallicity star candidates from the Southern Photometric Local Universe Survey (S-PLUS…
Beyond spectroscopy. I. Metallicities, distances, and age estimates for over twenty million stars from SMSS DR2 and Gaia EDR3
Yang Huang, Timothy C. Beers, Christian Wolf +8
Accurate determinations of stellar parameters and distances for large complete samples of stars are keys for conducting detailed studies of the formation and evolution of our Galax…
Bright Metal-Poor Stars from the Hamburg/ESO Survey. II. A Chemodynamical Analysis
Timothy C. Beers, Vinicius M. Placco, Daniela Carollo +6
We obtain estimates of stellar atmospheric parameters for a previously published sample of 1777 relatively bright (9 < B < 14) metal-poor candidates from the Hamburg/ESO Survey. Th…
Spectroscopic Survey of G and K Dwarfs in the Hipparcos Catalog. I. Comparison between the Hipparcos and Photometric Parallaxes
Bokyoung Kim, Deokkeun An, John R. Stauffer +3
The tension between the Hipparcos parallax of the Pleiades and other independent distance estimates continues even after the new reduction of the Hipparcos astrometric data and the…
Modelling the observed properties of carbon-enhanced metal-poor stars using binary population synthesis
C. Abate, O. R. Pols, R. J. Stancliffe +4
The stellar population in the Galactic halo is characterised by a large fraction of CEMP stars. Most CEMP stars are enriched in -elements (CEMP- stars), and some of these are…
Metal-Poor Stars Observed with the Magellan Telescope. III. New Extremely and Ultra Metal-Poor Stars from SDSS/SEGUE and Insights on the Formation of Ultra Metal-Poor Stars
Vinicius M. Placco, Anna Frebel, Young Sun Lee +5
We report the discovery of one extremely metal-poor (EMP; [Fe/H]<-3) and one ultra metal-poor (UMP; [Fe/H]<-4) star selected from the SDSS/SEGUE survey. These stars were identified…
The Frequency of Field Blue-Straggler Stars in the Thick Disk and Halo System of the Galaxy
Rafael M. Santucci, Vinicius M. Placco, Silvia Rossi +5
We present an analysis of a new, large sample of field blue-straggler stars (BSSs) in the thick disk and halo system of the Galaxy, based on stellar spectra obtained during the Slo…
