Hadronic and quark matter - applications in astrophysics
Oral presentation
Relativistic binary systems showing the ablation of the donor star by
pulsar winds have been discovered in 1988 and studied recently using
FermiLat and other facilities. We discuss in this presentation the
evolution of the "black widow" systems, showing that theoretical
tracks reveal i) the importance of illumination feedback of X rays
onto the donor star, ii) a long (several Gyr) overall...

Hadronic and quark matter - applications in astrophysics
Oral presentation
Ultra-high energy cosmic rays (UHECR) are the highest energy messengers of the present universe, with energies up to $10^{20}$ eV. Studies of astrophysical particles (hadrons, neutrinos and photons) at their highest observed energies have implications for fundamental physics as well as astrophysics. The primary particles interacts in the atmosphere and generates an extensive air shower....

Hadronic and quark matter - applications in astrophysics
Oral presentation
The pasta phase in core-collapse supernova matter (finite temperatures and fixed pro-
ton fractions) is studied within relativistic mean field models. Three different calculations
are used for comparison, the Thomas-Fermi (TF), the Coexistence Phase (CP) and the
Compressible Liquid Drop (CLD) approximations. The effects of including light clusters in
nuclear matter and the densities at...

Hadronic and quark matter - applications in astrophysics
Oral presentation
In the present paper we employ the quark-meson coupling model
(QMC) to investigate the onset of the pasta phase
in nuclear matter under conditions such as those
expected in neutron star crusts.
Pasta is obtained with fixed proton fractions and for beta equilibrated
matter.
We probe our results into restrictions imposed on the
the values of the density and pressure at the inner edge...
