New Universal Relations for Magnetized Neutron Stars

Byon N. Jayawiguna, Siddarth Ajith, Takuya Katagiri +2

Unlike the neutron-star mass--radius relation, which depends sensitively on the internal stellar structure through the equation of state of dense nuclear matter, certain neutron-st…

Holographic Thermodynamics of Dyonic Dilaton AdS Black Holes

Muhammad Fitrah Alfian Rangga Sakti, Robert Mann, Piyabut Burikham

We investigate the holographic dual of the extended bulk thermodynamics of dyonic dilaton AdS black holes by allowing both the cosmological constant and Newton's gravitational cons…

Entropy Quantization and Quasi-normal Modes of Dyonic Kerr-Sen Black Holes

Muhammad Fitrah Alfian Rangga Sakti, Piyabut Burikham

We explore the properties of inner and outer horizon thermodynamics of dyonic Kerr-Sen black hole (DKSBH). It is observed that the entropy (or area) product is universal, depending…

Quasi-bound States of Scalar field inside the Dyonic Kerr-Sen Black Hole

David Senjaya, Tinnagrit Songkeaw, Piyabut Burikham

We found sets of exact analytic quasi-stationary states of a massive scalar field in a dyonic Kerr-Sen black hole~(DKSBH) background in the maximally extended spacetime region. A c…

Thermodynamics and Geometrical Optics of Reissner Nordstrom de Sitter Black Holes in Noncommutative Geometry

Phongsakorn Sereewat, David Senjaya, Piyabut Burikham

We investigate the thermodynamic, optical, and dynamical properties of Reissner-Nordstrom-de Sitter black holes in a noncommutative spacetime with a minimal length scale Theta. Wit…

Theory space and stability analysis of General Relativistic cosmological solutions in modified gravity

Saikat Chakraborty, Piyabut Burikham

Some aspects of two General Relativistic cosmological solutions, an exact CDM-like cosmological solution ( is cosmographic jerk parameter), and a specifically designed…
