J-PLUS: Searching for very metal-poor star candidates using the SPEEM pipeline
Carlos Andrés Galarza, Simone Daflon, Vinicius M. Placco +25
We explore the stellar content of the Javalambre Photometric Local Universe Survey (J-PLUS) Data Release 2 and show its potential to identify low-metallicity stars using the Stella…
J-PLUS: Identification of low-metallicity stars with artificial neural networks using SPHINX
D. D. Whitten, V. M. Placco, T. C. Beers +24
We present a new methodology for the estimation of stellar atmospheric parameters from narrow- and intermediate-band photometry of the Javalambre Photometric Local Universe Survey…
Deep SDSS Optical Spectroscopy of Distant Halo Stars. III. Chemical analysis of extremely metal-poor stars
E. Fernandez-Alvar, C. Allende Prieto, T. C. Beers +3
We present the results of an analysis for 107 extremely metal-poor (EMP) stars with metallicities less than [Fe/H] = -3.0, identified from medium-resolution spectra in SDSS. We fol…
Deep SDSS optical spectroscopy of distant halo stars II. Iron, calcium, and magnesium abundances
E. Fernández-Alvar, C. Allende Prieto, K. J. Schlesinger +11
We analyze a sample of 3,944 low-resolution (R ~ 2000) optical spectra from the Sloan Digital Sky Survey (SDSS), focusing on stars with effective temperatures 5800 < Teff < 6300 K,…
A Machine Learning Method to Infer Fundamental Stellar Parameters from Photometric Light Curves
A. A. Miller, J. S. Bloom, J. W. Richards +6
A fundamental challenge for wide-field imaging surveys is obtaining follow-up spectroscopic observations: there are > photometrically cataloged sources, yet modern spectrosc…
Deep SDSS optical spectroscopy of distant halo stars I. Atmospheric parameters and stellar metallicity distribution
C. Allende Prieto, E. Fernandez-Alvar, K. J. Schlesinger +14
We analyze a sample of tens of thousands of spectra of halo turnoff stars, obtained with the optical spectrographs of the Sloan Digital Sky Survey (SDSS), to characterize the stell…
