The Peekaboo galaxy: new SALT spectroscopy and implications of archive HST data
Alexei Kniazev, Simon Pustilnik
The dwarf galaxy Peekaboo was recently identified as a Local Volume (LV) gas-rich and 'eXtremely Metal-Poor' (XMP) dIrr. Its gas metallicity is Z~Zsun/50, with +/-1 uncertainty…
Peculiarities of the chemical enrichment of metal-poor Stars in the Milky Way Galaxy
T. Mishenina, M. Pignatari, I. Usenko +5
The oldest stars in the Milky Way are metal-poor with [Fe/H] < -- 1.0, displaying peculiar elemental abundances compared to solar values. The relative variations in the chemical co…
Lithium Cepheid V708 Car with an unusual chemical composition
V. V. Kovtyukh, S. M. Andrievsky, K. Werner +2
The purpose of this work is to spectroscopically analyse the classical Cepheid V708 Car. A preliminary check of the spectrum of V708 Car showed that this is a lithium-rich supergia…
Horizontal branch structure, age, and chemical composition for very metal-poor extragalactic globular clusters
M. E. Sharina, M. I. Maricheva, A. Y. Kniazev +2
This paper presents the results of analysing the integrated light (IL) low-resolution spectra of globular clusters (GCs) in the M31 and Centaurus A groups of galaxies. The sample c…
Stellar feedback impact on the ionized gas kinematics in the dwarf galaxy Sextans B
Ivan S. Gerasimov, Oleg . V. Egorov, Alexei V. Moiseev +3
We investigated the ionised and atomic gas kinematics and excitation state in the central region of ongoing star formation of the nearby low-metallicity dwarf galaxy Sextans B. The…
Isolated dSph galaxy KKs3 in the local Hubble flow
I. D. Karachentsev, A. Yu. Kniazev, M. E. Sharina
We present the SALT spectroscopy of a globular cluster in the center of the nearby isolated dSph galaxy KKs3 situated at a distance of 2.12 Mpc. Its heliocentric radial velocity is…
