Homogeneity in the early chemical evolution of the Sextans dwarf Spheroidal galaxy

R. Lucchesi, C. Lardo, F. Primas +10

We present the high-resolution spectroscopic analysis of two new extremely metal-poor stars (EMPS) candidates in the dwarf spheroidal galaxy Sextans. These targets were pre-selecte…

The chemical evolution of the dwarf Spheroidal galaxy Sextans

R. Theler, P. Jablonka, R. Lucchesi +11

We present the analysis of the FLAMES dataset targeting the central 25 arcmin region of the Sextans dSph. This dataset is the third major part of the high resolution spectroscopic…

The formation of the Milky Way halo and its dwarf satellites, a NLTE-1D abundance analysis. I. Homogeneous set of atmospheric parameters

L. Mashonkina, P. Jablonka, Yu. Pakhomov +2

We present a homogeneous set of accurate atmospheric parameters for a complete sample of very and extremely metal-poor stars in the dwarf spheroidal galaxies (dSphs) Sculptor, Ursa…

The early days of the Sculptor dwarf spheroidal galaxy

P. Jablonka, P. North, L. Mashonkina +11

We present the high resolution spectroscopic study of five -3.9<=[Fe/H]<=-2.5 stars in the Local Group dwarf spheroidal, Sculptor, thereby doubling the number of stars with compara…

Spectroscopy of extended Lyα envelopes around z=4.5 quasars

P. L. North, F. Courbin, A. Eigenbrod +1

What are the frequency, shape, kinematics, and luminosity of Lyα envelopes surrounding radio-quiet quasars at high redshift, and is the luminosity of these envelopes related to tha…

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…
