Multivariate analysis of the globular clusters in M87
Sukanta Das, Tanuka Chattopadhyay, Emmanuel Davoust
An objective classification of 147 globular clusters in the inner region of the giant elliptical galaxy M87 is carried out with the help of two methods of multivariate analysis. Fi…
Stellar populations in Centauri: a multivariate analysis
Didier Fraix-Burnet, E. Davoust
We have performed multivariate statistical analyses of photometric and chemical abundance parameters of three large samples of stars in the globular cluster Centauri. The stati…
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…
Formation of dwarf ellipticals and dwarf irregular galaxies by interaction of giant galaxies under environmental influence
Tanuka Chattopadhyay, Suma Debsarma, Pradip Karmakar +1
A model is proposed for the formation of gas-rich dwarf irregular galaxies and gas-poor, rotating dwarf elliptical galaxies following the interaction between two giant galaxies as…
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.…
A search for RCB stars in globular clusters
Scarlett-Rose Boiardi, Sebastien Roger, Emmanuel Davoust
There are only about 65 R Coronae Borealis stars known in our Galaxy, and none in globular clusters. As these stars are thought to result from the merger of two white dwarfs, one w…
