General Relativistic effects on the conversion of nuclear to two-flavour quark matter in compact stars
Abhijit Bhattacharyya, Sanjay K. Ghosh, Ritam Mallick +1
We investigate the General Relativistic (GR) effects on the conversion from nuclear to two-flavour quark matter in compact stars, both static as well as rotating. We find that GR e…
Effect of General Relativity and rotation on the energy deposition rate for inside a compact star
Abhijit Bhattacharyya, Sanjay K. Ghosh, Ritam Mallick +1
We have studied the energy deposition rate in a rotating compact star. This reaction is important for the study of gamma ray bursts. The General Relativis…
The conversion of Neutron star to Strange star : A two step process
Abhijit Bhattacharyya, Sanjay K. Ghosh, Partha S. Joardar +2
The conversion of neutron matter to strange matter in a neutron star have been studied as a two step process. In the first step, the nuclear matter gets converted to two flavour qu…
QCD phase transition in rotaing neutron star, Neutrino beaming and Gamma-ray bursters
Abhijit Bhattacharyya, Sanjay K. Ghosh, Sibaji Raha
We have studied the emission of neutrinos from a rotating hybrid star. We find that the emission is predominantly confined to a very small angle, provided the core of the star is i…
Rotating Quark Star in Chiral Colour Dielectric Model
Abhijit Bhattacharyya, Sanjay K. Ghosh
The properties of rotating quark star is studied using the equation of state obtained from Chiral Colour Dielectric model. The results are compared with the MIT bag model results.…
Strangeness, Cosmological Cold Dark Matter and Dark Energy
Sibaji Raha, Shibaji Banerjee, Abhijit Bhattacharyya +5
It is now believed that the universe is composed of a small amount of the normal luminous matter, a substantial amount of matter (Cold Dark Matter: CDM) which is non-luminous and a…
Rotating Twin Stars and Signature of Quark-Hadron Phase Transition
Abhijit Bhattacharyya, Sanjay K. Ghosh, Matthias Hanauske +1
The quark hadron phase transition in a rotating compact star has been studied. The NLZ-model has been used for the hadronic sector and the MIT Bag model has been used for the quark…
Massive Compact Halo Objects from the Relics of the Cosmic Quark-Hadron Transition
Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +2
The existence of compact gravitational lenses, with masses around 0.5 (M_{\odot}), has been reported in the halo of the Milky Way. The nature of these dark lenses is as yet obscure…
Relics of Cosmic Quark- Hadron Phase Transition and Massive Compact Halo Objects
Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +3
We propose that the cold dark matter (CDM) is composed entirely of quark matter, arising from a cosmic quark-hadron transition. We show that compact gravitational objects, with mas…
Bose-Einstein condensation in dense nuclear matter and strong magnetic fields
Prantick Dey, Abhijit Bhattacharyya, Debades Bandyopadhyay
Bose-Einstein condensation of antikaons in cold and dense beta-equilibrated matter under the influence of strong magnetic fields is studied within a relativistic mean field model.…
The Cosmic QCD Phase Transition, Quasi-baryonic Dark Matter and Massive Compact Halo Objects
Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +3
We propose that the cold dark matter (CDM) is composed entirely of quark matter, arising from a cosmic quark-hadron transition. We denote this phase as "quasibaryonic", distinct fr…
The Cosmological Quark-Hadron Transition and Massive Compact Halo Objects
Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +2
One of the abiding mysteries in the so-called standard cosmological model is the nature of the dark matter. It is universally accepted that there is an abundance of matter in the u…
