Isolated neutron stars can emit gravitational waves via a variety of mechanisms. These emission channels are highly sensitive to the nature of matter in the star, and can potentially reveal information on the high density equation of state not accessible via other means. In this talk I will review these mechanisms, and discuss how they relate to the microphysics of the stellar matter. I will...

This talk will provide an update on gravitational wave emission from isolated neutron stars and on the dynamics of the associated unstable oscillation modes.

Recently it was shown that a phase transition to deconfined quark matter can lead to the formation of a novel kind of third family of compact stars, that is present only in the hot, early stages of their evolution. Such a feature can be related to unusual thermal properties of the equation of state in the phase coexistence region, which manifest themselves as a negative slope of the phase...

In this talk I will present the current state of mass and radius measurements of neutron stars in low mass X-ray binaries obtained during thermonuclear X-ray bursts or in quiescence. Taking into account a number of systematic uncertainties that may be present in
the measurements as well as the results of recent theoretical calculations we obtain strong and quantitative constraints on...

Magnetars are highly magnetized neutron star and energetic X-ray/ soft gamma ray bursts are often observed from these sources. The most energetic of these bursts,- the giant flares have been observed only from a few sources and exhibit distinct observational characteristics. The 2011 outburst of the relatively low magnetic field magnetar was quite extraordinary because of the unusual timing...

We examine the role of a dipole-type magnetic field of a compact (neutron) star for its interaction with the ambient interstellar medium, and the resulting drag as the star orbits near a supermassive black hole. The enhancement of the orbital decay is found to be very small in the Galactic centre (the mini-spiral region of Sgr A*), where the environment density is very low, but it becomes...

I shall discuss a number of subjects including the equation of state of uniform nucleonic matter, collective oscillations in the inner crust of neutron stars, the neutron superfluid density in the inner crust, elastic properties of the crust, induced interactions between nucleons and the transition to quark matter.

Recently we have explored the properties of an interacting fermionic compact star in a 1+4 dimensional Kaluza--Klein-like spacetime, where an extra microscopical spacelike dimension was introduced (See Sz. Karsai's talk). Here, we present wether we would able to measure the effect of these extra dimensions by gravitational wave detectors.

Multi-wavelength observations over the last decades proved the existence of observationally very diverse manifestations of isolated NSs (INSs) and led to the separation of INSs into distinct classes. Most of the ~2,300 known INSs are radio pulsars with periods P < 8 s and magnetic field B ~ 10 12 G, but there are objects with much greater potential for understanding the INSs diversity. This...

I will review several ongoing projects which aim at examining how astrophysical observations of neutron stars (mass, radius, spin frequency, thermal emission and evolution,...) may constrain the properties and composition of neutron star matter.

A step towards to understanding how radiative processes give rise to the rich set of variability features, namely the quasi-periodic oscillations, actually seen in the X-ray light curves of low-mass X-ray binaries is given by the study of the energy and frequency dependence of the phase lags of the QPOs in the light curves. Here we studied the phase lags of all QPOs in the range of 1 Hz to...
