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…
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…
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…
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 relationship between metallicity distributions of globular clusters and of circumgalactic gas
I. A. Acharova, M. E. Sharina
The abundance of alpha elements and iron in stars of globular clusters shows the composition of the gaseous medium, in which they have been formed. In the present paper, we discuss…
Galactic Constraints on Supernova Progenitor Models
I. Acharova, B. Gibson, Yu. Mishurov +1
We undertake a statistical analysis of the radial abundance distributions in the Galactic disk within a theoretical framework for Galactic chemical evolution which incorporates the…
