Indicatives of Early Stages of Star Formation in the Universe
Irina Acharova, Margarita Sharina
The paper analyzes formation conditions for globular clusters (GCs) in circumgalactic clouds. The similarity between the metallicity distributions of GCs in the nearby Universe and…
Spectroscopy of globular clusters in the dwarf spheroidal galaxy IKN
M. E. Sharina, V. V. Shimansky
Moderate resolution spectra of four globular clusters in the dwarf spheroidal galaxy IKN obtained with the 6-m telescope of the Special Astrophysical Observatory have been used to…
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…
Surface photometry of dwarf irregular galaxies in different environments
M. E. Sharina
Surface photometry data on 90 dwarf irregular galaxies (dIrrs) in a wide vicinity of the Virgo cluster and 30 isolated dIrrs are presented. Images from the Sloan Digital Sky Survey…
Gradients of metallicity and age of stars in the dwarf spheroidal galaxies KKs3 and ESO269-66
M. E. Sharina, L. N. Makarova, D. I. Makarov
We compare the properties of the stellar populations of the globular clusters and field stars in two dwarf spheroidal galaxies (dSphs): ESO269-66, a near neighbor of the giant S0 g…
Globular Clusters Lost by the Sagittarius Dwarf Spheroidal Galaxy
N. R. Arakelyan, S. V. Pilipenko, M. E. Sharina
In this work a search was carried out for globular clusters belonging to the Sagittarius (Sgr) tidal stream using the analysis of spatial positions, radial velocities relative to t…
Evolutionary link between globular clusters and circumgalactic clouds
I. A. Acharova, M. E. Sharina
The established by us possibility to consider circumgalactic clouds (CGCs) as the remnants of the parent clouds in which globular clusters (GCs) have been formed (Acharova & Sharin…
On the influence of multiple stellar populations in globular clusters on their medium-resolution integrated-light spectra
M. E. Sharina, V. V. Shimansky
We take a closer look at our published results of determination of ages, metallicities, helium mass fractions and abundances of chemical elements in Galactic globular clusters in o…
The Stellar Population and Orbit of the Galactic Globular Cluster Palomar 3
M. E. Sharina, M. V. Ryabova, M. I. Maricheva +1
Deep stellar photometry of one of the most distant Galactic globular clusters, Palomar 3, based on frames taken with the VLT in Johnson-Cousins broadband V and Ifilters is presente…
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…
Gemini spectroscopy of the outer disk star cluster BH176
M. E. Sharina, C. J. Donzelli, E. Davoust +2
BH176 is an old metal-rich star cluster. It is spatially and kinematically consistent with belonging to the Monoceros Ring. It is larger in size and more distant from the Galactic…
Modeling and Analysis of a Spectrum of the Globular Cluster NGC 2419
M. E. Sharina, V. V. Shimansky, E. Davoust
NGC 2419 is the most distant massive globular cluster in the outer Galactic halo. It is unusual also due to the chemical peculiarities found in its red giant stars in recent years.…
