Clustering of eclipsing binary light curves through functional principal component analysis
Soumita Modak, Tanuka Chattopadhyay, Asis Kumar Chattopadhyay
In this paper, we revisit the problem of clustering 1318 new variable stars found in the Milky way. Our recent work distinguishes these stars based on their light curves which are…
Investigation of the Effect of Bars on the Properties of Spiral Galaxies: A Multivariate Statistical Study
Prasenjit Banerjee, Tanuka Chattopadhyay, Asis Kumar Chattopadhyay
Subjective classification of spiral galaxies is not sufficient for studying the effect of bars on their physical characteristics. In reality the problem is to comprehend the comple…
Role of galactic bars in the formation of spiral arms: A study through orbital and escape dynamics -- I
Debasish Mondal, Tanuka Chattopadhyay
In the present work we have developed a three-dimensional gravitational model of barred galaxies, in order to study orbital and escape dynamics of the stars inside their central ba…
Exploration about the origin of galactic and extragalactic star clusters through simulated H-R diagrams
Tanuka Chattopadhyay, Sreerup Mondal, Suman Paul +2
The present work explores the origin of the formation of star clusters in our Galaxy and in Small Magellanic Cloud (SMC) through simulated H-R diagrams and compare those with obser…
Unsupervised Classification of Galaxies. I. ICA feature selection
Tanuka Chattopadhyay, Didier Fraix-Burnet, Saptarshi Mondal
Subjective classification of galaxies can mislead us in the quest of the origin regarding formation and evolution of galaxies since this is necessarily limited to a few features. T…
