Elemental abundances in the center of the Galactic Nuclear Disc
V. V. Kovtyukh, S. M. Andrievsky, R. P. Martin +5
We have made the first attempt to derive the chemical properties of the Galactic disc at its very central part using high-resolution infrared spectroscopic observations of four cla…
Probing the existence of very massive first stars
S. Salvadori, P. Bonifacio, E. Caffau +4
We present a novel approach aimed at identifying the key chemical elements to search for the (missing) descendants of very massive first stars exploding as Pair Instability Superno…
Neutron Star Mergers Are the Dominant Source of the r-process in the Early Evolution of Dwarf Galaxies
Gina E. Duggan, Evan N. Kirby, Serge M. Andrievsky +1
There are many candidate sites of the r-process: core-collapse supernovae (including rare magnetorotational core-collapse supernovae), neutron star mergers, and neutron star/black…
Barium abundance in the central part of the dSph Fornax galaxy
S. M. Andrievsky, S. A. Korotin, V. Hill +1
We revisited barium abundance in a sample of giant stars in the dwarf spheroidal Fornax galaxy. Non-local thermodynamic equilibrium (NLTE) synthesis was used to derive the barium a…
Oxygen, -element and iron abundance distributions in the inner part of the Galactic thin disc. II
S. M. Andrievsky, R. P. Martin, V. V. Kovtyukh +2
We have derived the abundances of 36 chemical elements in one Cepheid star, ASAS 181024--2049.6, located R kpc from the Galactic center. This star falls within a re…
Mn abundances in the stars of the Galactic disc with metallicities -1.0 < [Fe/H] < 0.3
T. Mishenina, T. Gorbaneva, M. Pignatari +2
In this work we present and discuss the observations of the Mn abundances for 247 FGK dwarfs, located in the Galactic disc with metallicity -1<Fe/H]<+0.3. The observed stars belong…
