Journal ArticleDOI
The NIR Ca II triplet at low metallicity: Searching for extremely low-metallicity stars in classical dwarf galaxies
Else Starkenburg,Vanessa Hill,Eline Tolstoy,J. I. González Hernández,J. I. González Hernández,Mike Irwin,Amina Helmi,Giuseppina Battaglia,Pascale Jablonka,M. Tafelmeyer,Matthew Shetrone,K. A. Venn,T. J. L. de Boer +12 more
TL;DR: In this article, the authors present results of synthetic spectral analysis of the Ca II triplet, that is focused on a better understanding of spectroscopic measurements of low-metallicity giant stars.
Journal ArticleDOI

TL;DR: In this paper, the results of a dedicated search for extremely metal-poor stars in the Fornax, Sculptor, and Sextans dSphs were presented.
Journal ArticleDOI
Chemical composition of extremely metal-poor stars in the Sextans dwarf spheroidal galaxy
Wako Aoki,Nobuo Arimoto,Kozo Sadakane,Eline Tolstoy,Giuseppina Battaglia,Pascale Jablonka,Matthew Shetrone,B. Letarte,Mike Irwin,Vanessa Hill,P. François,Kim Venn,Francesca Primas,Amina Helmi,Andreas Kaufer,M. Tafelmeyer,Thomas Szeifert,Carine Babusiaux +17 more
TL;DR: In this paper, the chemical abundances of six extremely metal-poor stars in the Sextans dwarf spheroidal galaxy were determined based on high resolution spectroscopy (R=40 000) with the Subaru Telescope High Dispersion Spectrograph.
Journal ArticleDOI
