Extremely metal-poor stars in classical dwarf spheroidal galaxies: Fornax, Sculptor and Sextans
M. Tafelmeyer, P. Jablonka, V. Hill +13
We present the results of a dedicated search for extremely metal-poor stars in the Fornax, Sculptor and Sextans dSphs. Five stars were selected from two earlier VLT/Giraffe and HET…
Direct detection of galaxy stellar halos : NGC 3957 as a test case
P. Jablonka, M. Tafelmeyer, F. Courbin +1
We present a direct detection of the stellar halo of the edge-on S0 galaxy NGC 3957, using ultra-deep VLT/VIMOS V and R images. This is achieved with a sky subtraction strategy bas…
The NIR Ca II triplet at low metallicity - Searching for extremely low-metallicity stars in classical dwarf galaxies
Else Starkenburg, Vanessa Hill, Eline Tolstoy +9
The NIR Ca II triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group, providing a better…
Chemical Composition of Extremely Metal-Poor Stars in the Sextans Dwarf Spheroidal Galaxy
W. Aoki, N. Arimoto, K. Sadakane +15
Chemical abundances of six extremely metal-poor ([Fe/H]<-2.5) stars in the Sextans dwarf spheroidal galaxy are determined based on high resolution spectroscopy (R=40,000) with the…
