Emission and cooling of a newborn quark star
Mikalai Prakapenia, Gregory Vereshchagin
It has long been believed that newborn quark stars are inefficient emitters because the quark plasma frequency is so high that it suppresses electromagnetic radiation across the en…
Pair luminosity and cooling of newborn strange star: Color-flavor-locked and two-flavor color superconducting quarks
Mikalai Prakapenia, Cheng-Jun Xia, Gregory Vereshchagin
Following the previous wor k[1] here we consider early thermal evolution of hot strange stars made of color superconducting quarks in two different pairing states: two-flavor color…
Pair luminosity and cooling of newborn strange star: unpaired quarks
Mikalai Prakapenia, Gregory Vereshchagin
It was shown that pair luminosity of the newborn strange star with temperature of K may be as high as erg/s. The question remains: can a strange sta…
Pair creation from radial electromagnetic perturbation of a compact astrophysical object
Mikalai Prakapenia, Gregory Vereshchagin
Recently Usov's mechanism of pair creation on the surface of compact astrophysical objects has been revisited [1] with a conclusion that the pair creation rate was previously under…
Pair creation in hot electrosphere of compact astrophysical objects
Mikalai Prakapenia, Gregory Vereshchagin
The mechanism of pair creation in electrosphere of compact astrophysical objects such as quark stars or neutron stars is revisited, paying attention to evaporation of electrons and…
Pauli blocking effects on pair creation in strong electric field
Mikalai Prakapenia, Gregory Vereshchagin
The process of electron-positron pair creation and oscillation in uniform electric field is studied, taking into account Pauli exclusion principle. Generally, we find that pair cre…
Numerical scheme for evaluating the collision integrals for triple interactions in relativistic plasma
M. A. Prakapenia, I. A. Siutsou, G. V. Vereshchagin
Binary interactions in relativistic plasma, such as Coulomb and Compton scattering as well as pair creation and annihilation are well known and studied in details. Triple interacti…
Pauli blocking effects in thermalization of relativistic plasma
M. A. Prakapenia, G. V. Vereshchagin
We investigate the effects of Pauli blocking on thermalization process of relativistic plasma by solving relativistic Uehling-Uhlenbeck equations with QED collision integral for al…
Bose-Einstein condensation in relativistic plasma
M. A. Prakapenia, G. V. Vereshchagin
The phenomenon of Bose-Einstein condensation is traditionally associated with and experimentally verified for low temperatures: either of nano-Kelvin scale for alkali atoms [1-3] o…
Thermalization of electron-positron plasma with quantum degeneracy
M. A. Prakapenia, I. A. Siutsou, G. V. Vereshchagin
The non-equilibrium electron-positron-photon plasma thermalization process is studied using relativistic Boltzmann solver, taking into account quantum corrections both in non-relat…
Numerical scheme for treatment of Uehling-Uhlenbeck equation for two-particle interactions in relativistic plasma
M. A. Prakapenia, I. A. Siutsou, G. V. Vereshchagin
We present a new efficient method to compute Uehling-Uhlenbeck collision integral for all two-particle interactions in relativistic plasma with drastic improvement in computation t…
