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…
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…
Unveiling short period binaries in the inner VVV bulge
E. Botan, R. K. Saito, D. Minniti +5
Most of our knowledge about the structure of the Milky Way has come from the study of variable stars. Among the variables, mimicking the periodic variation of pulsating stars, are…
Two new pulsating low-mass pre-white dwarfs or SX Phenix stars?*
M. A. Corti, A. Kanaan, A. H. Córsico +4
Context. The discovery of pulsations in low-mass stars opens an opportunity for probing their interiors and to determine their evolution, by employing the tools of asteroseismology…
Magnetic White Dwarf Stars in the Sloan Digital Sky Survey
S. O. Kepler, Ingrid Pelisoli, Stefan Jordan +10
To obtain a better statistics on the occurrence of magnetism among white dwarfs, we searched the spectra of the hydrogen atmosphere white dwarf stars (DAs) in the Data Release 7 of…
Empirical Determination of Convection Parameters in White Dwarfs I : Whole Earth Telescope Observations of EC14012-1446
J. L. Provencal, M. H. Montgomery, A. Kanaan +55
We report on analysis of 308.3 hrs of high speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth Telescope (WET) during…
