Constraints on temporal variation of fundamental constants from GRBs
C. Bambi, A. Drago
The formation of a strange or hybrid star from a neutron star progenitor is believed to occur when the central stellar density exceeds a critical value. If the transition from hadr…
Formation of Quark Phases in compact stars and their connection to Gamma-Ray-Bursts
A. Drago, G. Pagliara, J. Schaffner-Bielich
We analyse the occurrence of quiescent times in the temporal structure of the Gamma-Ray-Bursts (GRBs) light curves. We show that if a long quiescent time is present, it is possible…
Softening of the equation of state of matter at large densities and temperatures: chiral symmetry restoration vs. quark deconfinement
Luca Bonanno, Alessandro Drago, Andrea Lavagno
We discuss two models for describing the behavior of matter at large densities and intermediate temperatures. In both models a softening of the equation of state takes place due to…
A compact star rotating at 1122 Hz and the r-mode instability
Alessandro Drago, Giuseppe Pagliara, Irene Parenti
We show that r-mode instabilities severely constraint the composition of a compact star rotating at a submillisecond period. In particular, the only viable astrophysical scenario f…
Transition to Quark Matter and long Gamma Ray Bursts
Alessandro Drago, Giuseppe Pagliara, Irene Parenti
The energy released by the inner engine of GRBs can originate from structural readjustments inside a compact star. In particular, the formation of deconfined quark matter can liber…
