Magnetized neutron stars: perturbative versus fully-numerical approaches
Debarati Chatterjee, Daw Guttmann, Jérôme Novak +2
(1) Background: for the study of highly magnetized neutron stars observed as magnetars, and to quantify the effect of this intense magnetic field onto the star's structure and shap…
-mode Oscillations for Hyperons and H-dibaryons in Neutron Stars
Rajesh Maiti, Jesper Leong, Debarati Chatterjee +1
The fundamental (-mode) oscillations of neutron stars are studied within the quark meson coupling model, a relativistic Hartree-Fock theory of dense nuclear matter, which takes…
Fundamental oscillations as a tool to distinguish boson stars from neutron stars and black holes
Swarnim Shirke, Bikram Keshari Pradhan, Debarati Chatterjee +2
Massive boson stars are self-gravitating configurations of self-interacting scalar fields and can be modeled by a massive scalar field with a quartic self-interaction potential. It…
Investigating the role of nuclear parameters in Neutron Star oscillations: a model comparison
Rajesh Maiti, Debarati Chatterjee
Recent studies based on the relativistic mean field (RMF) model found certain nuclear empirical parameters, in particular the nucleon effective mass, to be strongly correlated with…
PSR J0614-3329: A NICER case for Strange Quark Stars
Swarnim Shirke, Rajesh Maiti, Debarati Chatterjee
Precise measurements of neutron star masses and radii by the NICER mission impose important constraints on the nuclear equation of state. The most recent NICER measurement of PSR J…
-mode oscillations in hot Neutron Stars: Effect of hyperons and neutrino trapping
Nilaksha Barman, Debarati Chatterjee
In this work, we present an equation of state formalism for hot Neutron Stars (NSs) which consistently includes the effects of finite temperature, hyperons as well as neutrino trap…
