A new approach to bulk viscosity in strange quark matter at high densities

- Physics
- 2009

A new method is proposed to compute the bulk viscosity in strange quark matter at high densities. Using the method it is straightforward to prove that the bulk viscosity is positive definite, which…

Surface structure of quark stars with magnetic fields

- Physics
- 2006

We investigate the impact of magnetic fields on the electron distribution of the electrosphere of quark stars. For moderately strong magnetic fields of B ∼ 1013 G, quantization effects are generally…

Asymmetric neutrino emission in quark matter and pulsar kicks

- Physics
- 2006

● Problem: If neutrinos are produced in a statistical and thermal equilibrium they can loose their polarization due to high interaction rates ( so called “nogo”-theorem, see e.g. Vilenkin) To check…

Stellar Stability in the Braneworld

We study the properties of astrophysical systems in a Brane World scenario. In particular, the consequences of local terms that emerge from extra-dimensional gravity are explored through the modified…

Is the universe homogeneous and isotropic in the time when quark-gluon plasma exists?

- Physics
- 2011

In this study, quark and strange quark matter which exist in the first seconds of the early Universe have been studied in the context of general relativity to be able to obtain space–time geometry of…

Lattice QCD Constraints on Hybrid and Quark Stars

We employ the constituent quark model and the generalized Pauli principle to compute the strange diquark interaction energies in quark–gluon plasma within the framework of an effective 4 theory. The…

Pulsar kicks by anisotropic neutrino emission from quark matter in strong magnetic fields

- Physics

Aims. We critically discuss a pulsar acceleration mechanism based on asymmetric neutrino emission from the direct quark Urca process in the interior of proto neutron stars. Methods. The neutrinos are…

Mass radius relation of compact stars in the braneworld

- Physics
- 2014

The braneworld scenario, based on the fact that the four dimension space-time is a hyper-surface of a five dimensional manifold, was shown to deal in a satisfactory way with the hierarchy problem. In…

Compact stars for undergraduates

The conditions for the appearance of stable quark stars and pion-condensed stars are analysed. On the basis of recently suggested equations of state such configurations can exist either as a third…

Small, dense quark stars from perturbative QCD

As a model for nonideal behavior in the equation of state of QCD at high density, we consider cold quark matter in perturbation theory. To second order in the strong coupling constant…

Pion condensation in cold dense matter and neutron stars

We study possible influence, on the neutron star structure, of a pion condensation occurring in cold dense matter. Several equations of state with pion-condensed phase are considered. The models of…
