Surface photometry of 50 dwarf galaxies in the Local Volume
K. A. Kryzhanovsky M. E. Sharina, I. D. Karachentsev, G. M. Karataeva
Results of surface photometry of 50 galaxies in the Local Volume based on archived images obtained with the Hubble Space Telescope are presented. Integrated magnitudes in the V and…
A nearby isolated dwarf: star formation and structure of ESO 006-001
Lidia N. Makarova, R. Brent Tully, Gagandeep S. Anand +4
Observations with the Hubble Space Telescope unexpectedly revealed that the dwarf galaxy ESO 006-001 is a near neighbor to the Local Group at a distance of 2.70 +- 0.11 Mpc. The st…
Investigation of the Prompt SNe Ia progenitor nature through the analysis of the chemical composition of globular clusters and circumgalactic clouds
Irina A. Acharova, Margarita E. Sharina, Egor A. Kazakov
A method is proposed for determining the properties of type Ia supernovae from short-lived precursors -- Prompt SNIa. This method is based on the assumption that this subtype of ty…
Analysis of integrated-light spectra of Galactic globular clusters
M. E. Sharina, V. V. Shimansky, N. N. Shimanskaya
We present the results of determination of the age, helium mass fraction (Y) in terms of the used stellar evolutionary models, metallicity ([Fe/H]), and abundances of the elements…
Age and chemical composition of the globular cluster NGC 6652
M. E. Sharina, V. V. Shimansky
We present the results of determination of the age, helium mass fraction (Y), metallicity ([Fe/H]), and abundances of the elements C, N, O, Na, Mg, Ca, Ti, C and Mn for the Galacti…
Modeling and analysis of medium-resolution integrated-light spectra of globular clusters in dwarf galaxies
M. E. Sharina, V. V. Shimansky
The study of ages, helium mass fraction (Y) and chemical composition of globular clusters in dwarf galaxies is important for understanding the physical conditions at the main evolu…
