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…
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…
Slowly Rotating and Tidal Deformation of Nonlocal Modified Tolman VII Star
Byon N. Jayawiguna, Piyabut Burikham
We investigate the moment of inertia, quadrupole deformation, and tidal deformation within the framework of nonlocal gravity, utilizing the exact modified Tolman-VII (NEMTVII) dens…
Scalar Instabilities Inside The Extremal Dyonic Kerr-Sen Black Hole: Novel Exact Solutions and Chronology Protection Conjecture
David Senjaya, Teephatai Bunyaratavej, Piyabut Burikham
We investigate the stability of test scalar fields in the region inside the extremal Dyonic Kerr-Sen black hole (DKSBH) horizon, where closed timelike curves exist. We successfully…
The effective phase space and -folding of the Starobinsky and extended Starobinsky model of inflation
Theppawan Rukpakawong, Piyabut Burikham
For zero spatial curvature, cosmological phase space of Starobinsky and extended Starobinsky inflationary model show three apparent attractors; the fixed angle attractor in the lar…
Revisiting Chronology Protection Conjecture in The Dyonic Kerr-Sen Black Hole Spacetime
Teephatai Bunyaratavej, Piyabut Burikham, David Senjaya
The Chronology Protection Conjecture (CPC) was first introduced by Hawking after his semi-classical investigation to the behaviour of a spacetime with closed timelike curves (CTCs)…
