Anisotropic Heat Transfer inside Rotating Neutron Stars
C. Y. Hui, K. S. Cheng
We have developed the anisotropic heat transport equation for rotating neutron stars. With a simple model of neutron star, we also model the propagation of heat pulses result from…
Accretion-Induced Conversion of High-Velocity Neutron Stars to Strange Stars in Supernovae and Implications for Gamma-Ray Bursts
K. S. Cheng, Z. G. Dai
We present a new model for gamma-ray bursts (GRBs) that are not only associated with supernovae but also have small baryon contamination. In this model, we assume a newborn neutron…
Can Rotational Properties of General Relativistic Compact Objects Be Predicted from Static Ones?
K. S. Cheng, T. Harko
We propose an approximate description of basic parameters (radius, mass and oblateness) of general relativistic compact rotating objects in terms of the parameters of the static co…
Energy Sources of Soft Gamma-Ray Repeaters
K. S. Cheng, Z. G. Dai
Quiescence and burst emission and relativistic particle winds of soft gamma-ray repeaters (SGRs) have been widely interpreted to result from ultrastrongly magnetized neutron stars.…
The polarization and beaming effect for GRBs
K. S. Cheng, J. H. Fan, Z. G. Dai
Both observations and theoretical models suggest that the emissions in gamma-ray bursts (GRBs) and the afterglows are beamed. We argue that the recent polarization measured in the…
Basic properties of Gamma-ray loud blazars
K. S. Cheng, J. H. Fan, L. Zhang
In this paper, a method is proposed to determine the basic properties of -ray loud blazars, among them the central black hole mass, M, the Doppler factor, , the propagation a…
