Distinct barium isotope ratios in CEMP-s and CEMP-rs stars
T. M. Sitnova, L. I. Mashonkina, A. M. Romanovskaya +2
We present a spectroscopic analysis of ten carbon enhanced metal-poor (CEMP) stars of type CEMP-s and CEMP-rs and determine their NLTE abundances of Ba and Eu, as well as the fract…
Unlocking the mystery of Sr synthesis in the early Galaxy through analysis of barium isotopes in very metal-poor stars
T. M. Sitnova, L. Lombardo, L. I. Mashonkina +8
We determine the contributions of the rapid (r) and slow (s) neutron capture processes to the Ba isotope mixture, along with Ba, Eu, and Sr NLTE abundances, in a sample of very met…
Slowly Rotating Peculiar Star BD+001659 as a Benchmark for Stratification Studies in Ap/Bp Stars
A. Romanovskaya, T. Ryabchikova, Y. Pakhomov +2
We present the results of a self-consistent analysis of the magnetic silicon star BD+001659, based on its high-resolution spectra taken from the ESPaDOnS archive (R = 68,00…
