Rotational parameters of strange stars in comparison with neutron stars
Manjari Bagchi
I study stellar structures the mass, the radius, the moment of inertia and the oblateness parameter at different spin frequencies for strange stars and neutron stars in a co…
Strange Stars : An interesting member of the compact object family
Manjari Bagchi, Subharthi Ray, Jishnu Dey +1
We have studied strange star properties both at zero temperature and at finite temperatures and searched signatures of strange stars in gamma-ray, x-ray and radio astronomy. We hav…
Importance of constraining the dense matter Equation of State in pulsar astrophysics
Manjari Bagchi
We study the dependence of the surface magnetic fields of radio pulsars on the choice of Equations of State, pulsar masses and the values of the angle between the magnetic axis and…
Bound for entropy and viscosity ratio for strange quark matter
Manjari Bagchi, Jishnu Dey, Mira Dey +4
High energy density ($\eps$) and temperature (T) links general relativity and hydrodynamics leading to a lower bound for the ratio of shear viscosity () and entropy density (…
Members of the double pulsar system PSR J0737-3039 : neutron stars or strange stars ?
Manjari Bagchi, Jishnu Dey, Sushan Konar +2
One interesting method of constraining the dense matter Equations of State is to measure the advancement of the periastron of the orbit of a binary radio pulsar (when it belongs to…
A three stage model for the inner engine of Gamma Ray Burst: Prompt emission and early afterglow
Jan Staff, Rachid Ouyed, Manjari Bagchi
We propose a new model within the ``Quark-nova'' scenario to interpret the recent observations of early afterglows of long Gamma-Ray Bursts (GRB) with the Swift satellite. This is…
Chromo-thermal oscillations and collapse of strange stars to black holes : Astrophysical Implications
Manjari Bagchi, Rachid Ouyed, Jan Staff +3
The effects of temperature on strange stars are studied and it is found that the maximum mass of the star decreases with the increase of temperature since at high temperatures the…
Evidence for strange stars from joint observation of harmonic absorption bands and of redshift
Manjari Bagchi, Subharthi Ray, Mira Dey +1
From recent reports on terrestrial heavy ion collision experiments it appears that one may not obtain information about the existence of asymptotic freedom (AF) and chiral symmetry…
Strange stars at finite temperature
Subharthi Ray, Manjari Bagchi, Jishnu Dey +1
We calculate strange star properties, using large N_c approximation with built-in chiral symmetry restoration (CSM). We used a relativistic Hartree Fock mean field approximation me…
Compact strange stars with a medium dependence in gluons at finite temperature
Manjari Bagchi, Subharthi Ray, Mira Dey +1
The possible existence of strange stars in the universe will help in the understanding of various properties of quantum chromodynamics, like asymptotic freedom and chiral symmetry…
Strange Pulsar Hypothesis
Raka Dona Ray Mandal, Monika Sinha, Manjari Bagchi +3
It appears that there is a genuine shortage of radio pulsars with surface magnetic fields significantly smaller than Gauss. We propose that the pulsars with very low ma…
Strange Star Equation of State With a Modified Richardson Potential
Manjari Bagchi, Subharthi Ray, Mira Dey +1
Richardson potential is an phenomenological interquark interaction taking care of two aspects of QCD, namely the asymptotic freedom and the confinement. The original potential has…
Newtonian and general relativistic contribution of gravity to surface tension of strange stars
Manjari Bagchi, Monika Sinha, Mira Dey +2
Surface tension (S) is due to the inward force experienced by particles at the surface and usually gravitation does not play an important role in this force. But in compact stars t…
