Addendum to ``Decoupling of pion coupling from quarks at high density in three models, and its possible observational consequences"
Manjari Bagchi, Monika Sinha, Mira Dey +1
The pions decouple from quarks while their coupling to nucleons remains unchanged at high density. This will have consequences for some recent papers.
High Density Strange Star Matter and Observed Parity Doubling of Excited Hadrons
Taparati Gangopadhyay, Manjari Bagchi, Mira Dey +2
Parity doubling is observed in hadron states around 1.5 GeV - and the estimated energy density is found to be high. When a large excitation energy is available and the pions decoup…
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…
