The construction of a realistic equation of state for dense matter as it can be found in core-collapse supernovae and neutron stars is a formidable task which is not yet completely achieved. The structure of very high density matter in the neutron star core is by far the most uncertain part of the EoS modeling. However, even in the least exotic regime of sub-saturation matter, where the...

The magnetic field strength at birth is arguably one of the most
important properties to determine the evolutionary path of a neutron
star. Objects with very high fields, collectively known as magnetars,
are characterized by high X-ray quiescent luminosities, outbursts,
and, for some of them, sporadic giant flares. While the magnetic field
strength is believed to drive their collective...

The network of Interferometric Gravitational wave detectors is entering in the so-called advanced phase. In few years from now Advanced LIGO and Advanced Virgo are expected to detect the gravitational waves emitted by a binary system of compact stars. The achievements of the initial interferometers, the scientific targets of the advanced and future 3rd generation observatories and the...

Observations of high magnetic field pulsars have shown that their thermal luminosity is systematically higher than that of classical radio-pulsars, thus confirming the idea that magnetic fields are involved in their X-ray emission. I review the present theory describing
the fully coupled evolution of temperature and magnetic field in neutron stars, and results from numerical simulations,...

We will review recent progress in the study of neutron star seismology, the excitation of rotational instabilities and the associate emission of gravitational waves. We will show the detectability limits of such instabilities for neutron stars emerging from collapse or the aftermath of binary mergers (afterglow). Finally, we will discuss recent progress in the study of neutron stars in...

We will discuss new results on nucleosynthesis in core-collapse supernovae and neutrino-driven winds that produce elements up to silver. Because the synthesis of these elements occurs closer to stability, in the near future, the nuclear physics uncertainties will be reduced by experiments. This will uniquely allow us to combine observations and nucleosynthesis calculations to constrain the...

Gravitational waves emitted by neutron stars in various astrophysical processes, have been shown to carry the imprint of the equation of state (EoS) of matter in the star inner core. I will discuss which are the perspectives of constraining the EoS of dense matter with the Advanced Virgo/LIGO detectors, expected to become operational within a year, and with the next generation of...

QCD is notoriously difficult to solve at nonzero baryon density, and most models or effective theories of dense quark or nuclear matter are restricted to a particular density regime and/or a particular form of matter. I will discuss the question
whether holographic methods can provide a realistic strong-coupling description of dense matter. In particular, I will ask the question whether the...

I will give a brief overview on thermodynamics and the phse structure
of QCD including recent developments from lattice QCD and effective
theory approach. The following selected issues will be discussed;
interplay between confinement and dynamical chiral symmetry breaking,
nuclear matter near chiral symmetry restoration, correlations between
light and heavy flavors.

Astronomers observe neutron stars in many guises. We see pulsars that emit regular radio, X-ray or gamma-ray signals. We observe systems that emit X-rays as they accrete matter from a binary companion. The observations allow us – at least in principle – to probe a regime of physics that can never be reached in terrestrial laboratories, allowing us to constrain the equation of state at...

For most of the known pulsars their emission is powered by the loss of the their rotational energy. The noncoherent, nonthermal emission has been detected form optical to TeV gamma-rays in >100 pulsars. In a few pulsars we also can see thermal radiation from the neutron star surface/atmosphere. I will review the properties of both components including their efficiencies, dependence of...

Soft Gamma-ray Repeaters (SGRs) and Anomalous X-ray pulsars (AXPs)
are peculiar X-ray sources which are believed to be magnetars:
ultra-magnetized neutron stars with surface field in excess of 10^14 G,
i.e. well above the QED threshold. For this reason their study has
far reaching implications for several fields of physics and astrophysics.
After summarizing the properties of these...

Newly-born millisecond magnetars are competing with black holes as source of the gamma-ray burst (GRB) power, mainly with their rotational energy reservoir. They may be formed both in the core-collapse of massive stars, and in the merger of neutron star or white dwarf binaries, or in the accretion-induced collapse of a white dwarf, being thus a plausible progenitor for long and short GRBs,...

Recent pulsar glitch observations indicating changing external torques, and developments in theory have opened a new perspective on neutron star structure and dynamics. Triggers and amplifiers of pulsar glitches; the roles of superfluidity and crust rigidity; the new perspectives required by the effects of Bloch entrainment; the coupling of sudden changes in internal and external torques and...
