Formation of quark phases in compact stars and SN explosion
Alessandro Drago, Giuseppe Pagliara, Giulia Pagliaroli +2
We describe possible scenarios of quark deconfinement in compact stars and we analyze their astrophysical implications. The quark deconfinement process can proceed rapidly, as a st…
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…
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…
Quark Deconfinement inside Compact Stars and Gamma Ray Bursts Inner Engine
Alessandro Drago, Giuseppe Pagliara, Irene Parenti
The temporal structure of Gamma Ray Bursts can be interpreted assuming as a inner engine a neutron star which undergoes a progressive compactification via production of strangeness…
Quark matter in compact stars?
Mark Alford, David Blaschke, Alessandro Drago +3
Ozel, in a recent reanalysis of EXO 0748-676 observational data (astro-ph/0605106), concluded that quark matter probably does not exist in the center of compact stars. We show that…
Burning of an hadronic star into a quark or a hybrid star
Alessandro Drago, Andrea Lavagno, Irene Parenti
We study the hydrodynamical transition from an hadronic star into a quark or a hybrid star. We discuss the possible mode of burning, using a fully relativistic formalism and realis…
