C-infinity Compact-Support Wormholes with Exact Schwarzschild Exterior in Trace-Coupled Gravity
Mushtaq Ahmad, M. Farasat Shamir, Ahdab K. Althukair
We study static, spherically symmetric traversable wormholes in trace-coupled gravity with action density f(R,T) = R + lambda T^2. The spacetime is built from C-infinity deformatio…
Periodic Timelike Motion and Gravitational Wave Signatures around a Magnetically Charged Black Hole Surrounded by Quintessence
R. H. Ali
We investigate timelike geodesics and gravitational wave signatures of periodic motion around a static magnetically charged black hole arising from nonlinear electrodynamics and im…
Odd-parity perturbations of trace-quadratic black holes with anisotropic matter: admissible branches, axial ringdown, and a coupled-PINN benchmark
Mushtaq Ahmad, M. Farasat Shamir, Adnan Malik +1
We study odd-parity gravitational perturbations of static black holes in trace-quadratic gravity supported by an anisotropic effective fluid with constant closure p…
Inflation from a Weyl-flat null origin
Malaika Arshad, Jehanzad Zafar, Ahdab Althukair +1
We show that a Weyl-flat null origin of inflation need not be in tension with present observations. For canonical single-field inflation, any background with $ε(N)\to ε_\infty\in(0…
New cases of super-flares on slowly rotating solar-type stars and large amplitude super-flares in G- and M-type main-sequence stars
A. k. Althukair, D. Tsiklauri
In our previous work, we searched for super-flares on different types of stars while focusing on G-type dwarfs using entire Kepler data to study statistical properties of the occur…
Prediction of short stellar activity cycles using derived and established empirical relations between activity and rotation periods
A. k. Althukair, D. Tsiklauri
In our previous work, we investigated the occurrence rate of super-flares on various types of stars and their statistical properties, with a particular focus on G-type dwarfs, usin…
Main-sequence star super-flares based on entire Kepler data
A. K. Althukair, D. Tsiklauri
We wrote and used an automated flare detection Python script to search for super-flares on main-sequence stars of types A, F, G, K, and M in Kepler's long-cadence data from Q0 to Q…
