Dark Matter Haloes and Rotation Curves via Brans-Dicke Theory
Hongsu Kim
In the present work, the Brans-Dicke (BD) theory of gravity is taken as a possible theory of k-essence. Then starting with the (already known) Brans-Dicke-Schwarzschild solution wh…
Brans-Dicke Theory as a Unified Model for Dark Matter - Dark Energy
Hongsu Kim
The Brans-Dicke (BD) theory of gravity is taken as a possible theory of k-essence coupled to gravity. It then has been realized that the BD scalar field does indeed play a role of…
Brans-Dicke Scalar Field as a Unique k-essence
Hongsu Kim
In the present work, the Brans-Dicke theory of gravity is taken as a possible theory of k-essence coupled to gravity and then the role played by the Brans-Dicke scalar field in rel…
Pulsar Magnetosphere : A General Relativistic Treatment
Hongsu Kim, Hyung Mok Lee, Chul H. Lee +1
A fully general relativistic description of the pulsar magnetosphere is provided. To be more concrete, a study of the pulsar magnetosphere is performed in the context of general re…
Charges and Magnetic Fields of the Slowly-rotating Neutron Stars
Hongsu Kim, Hyung Mok Lee, Chul H. Lee +1
In association with the Goldreich-Julian's magnetic braking mechanism to explain the luminosity of radio pulsars as a result of their spin-down, it is of some interest to explore h…
Removal of Closed Timelike Curves in Kerr-Newman Spacetime
Hongsu Kim
A simple yet systematic new algorithm to investigate the global structure of Kerr-Newman spacetime is suggested. Namely, the global structure of θ=const. timelike submanifolds of K…
