Observational constraints on the interacting dark energy - dark matter (IDM) cosmological models
T. Harko, K. Asadi, H. Moshafi +1
Particle creation (or annihilation) mechanisms, described by either quantum field theoretical models, or by the thermodynamics of irreversible processes, play an important role in…
Reply to [arXiv:1105.5147] "Are GRB 090423 and Similar Bursts due to Superconducting Cosmic Strings?"
K. S. Cheng, Yun-Wei Yu, T. Harko
The GRB outflow driven by superconducting cosmic strings is likely to be an arc rather than a usually-considered spherical cap. In such a case, the afterglows of the cosmic string…
Neutrino and Electron-positron Pair Emission from Phase-induced Collapse of Neutron Stars to Quark Stars
K. S. Cheng, T. Harko
We study the energy released from phase-transition induced collapse of neutron stars, which results in large amplitude stellar oscillations. To model this process we use a Newtonia…
Relativistic Mass Ejecta from Phase-transition-induced Collapse of Neutron Stars
K. S. Cheng, T. Harko, Y. F. Huang +3
We study the dynamical evolution of a phase-transition-induced collapse neutron star to a hybrid star, which consists of a mixture of hadronic matter and strange quark matter. The…
Thin accretion disks around neutron and quark stars
Z. Kovács, K. S. Cheng, T. Harko
The possibility of observationally discriminating between various types of neutron stars, described by different equations of state of the nuclear matter, as well as differentiatin…
