The formation of the Milky Way halo and its dwarf satellites: a NLTE-1D abundance analysis. IV. Segue 1, Triangulum II, and Coma Berenices UFDs
T. M. Sitnova, L. I. Mashonkina, A. M. Tatarnikov +6
We present atmospheric parameters and abundances for chemical elements from carbon to barium in metal-poor stars in Segue 1 (seven stars), Coma Berenices (three stars), and Triangu…
Differential Speckle Polarimetry of Betelgeuse in 2019-2020: the rise is different from the fall
Boris Safonov, Alexandr Dodin, Marina Burlak +6
Recently published episodic spectral (Levesque and Massey, 2020) and high angular resolution (Montarges et al, 2020) observations of Betelgeuse suggest that the deep minimum of 201…
Chemical composition of metal-poor stars in Coma Berenices ultra-faint dwarf galaxy as a proxy to individual chemical enrichment events
Tatyana Sitnova, Lyudmila Mashonkina, Andrey Tatarnikov +3
We present NLTE abundances and atmospheric parameters for three metal-poor stars ([Fe/H]<-2) in Coma Berenices ultra-faint dwarf galaxy (UFD). The derived results are based on new…
