Program package for the analysis of high resolution high signal-to-noise stellar spectra
N. Piskunov, T. Ryabchikova, Yu. Pakhomov +4
The program package SME (Spectroscopy Made Easy), designed to perform an analysis of stellar spectra using spectral fitting techniques, was updated due to adding new functions (iso…
The formation of the Milky Way halo and its dwarf satellites; a NLTE-1D abundance analysis. II. Early chemical enrichment
L. Mashonkina, P. Jablonka, T. Sitnova +2
We present the non-local thermodynamic equilibrium (NLTE) abundances of up to 10 chemical species in a sample of 59 very metal-poor (VMP, -4 < [Fe/H] < -2) stars in seven dwarf sph…
Impact of NLTE on determinations of atmospheric parameters and chemical abundances of very metal-poor stars
Lyudmila Mashonkina, Tatyana Sitnova, Yuri Pakhomov +1
Based on high-resolution spectral observations for a sample of very metal-poor stars, we investigate how well stellar chemical abundances can be derived with available theoretical…
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…
