Unravelling Mass Transfer in Algols from Surface Abundances. I. Z Vulpeculae
Ahmet Dervişoğlu, Simge Adalalı, Ferhat Güney +7
The photospheric abundance pattern of the components is a sensitive probe of mass and angular momentum transfer in Algols. With the aim to trace the evolutionary history and disclo…
Optical and Thermodynamic Signatures of Lorentz Symmetry Breaking in Bumblebee AdS Black Holes
Behzad Eslam Panah, Abdullah Guvendi, Semra Gurtas Dogan +1
We investigate the impact of spontaneous Lorentz symmetry breaking on scalar wave propagation, null geodesics, and thermodynamic behavior of four-dimensional asymptotically AdS bla…
Electromagnetic wave propagation in static black hole spacetimes: an effective refractive index description in Schwarzschild geometry
Abdullah Guvendi, Omar Mustafa Semra Gurtas Dogan, Hassan Hassanabadi
We investigate electromagnetic wave propagation in static, spherically symmetric black hole spacetimes using a covariant and gauge-invariant framework based on the established Maxw…
Schrödinger and Klein-Gordon oscillators in Eddington-inspired Born-Infeld gravity: Degree-one Confluent Heun polynomial correspondence
Omar Mustafa, Abdullah Guvendi
We investigate Schrödinger and Klein-Gordon (KG) oscillators in the spacetime of a global monopole (GM) within Eddington inspired Born-Infeld (EiBI) gravity, including, in the rela…
Two-body Dirac equation in DSR: results for fermion-antifermion pairs
Nosratollah Jafari, Abdullah Guvendi
This study investigates a modified two-body Dirac equation in (2+1)-dimensional spacetime, inspired by Amelino-Camelia's doubly special relativity (DSR). We begin by deriving a cov…
Scalar-Wave Signatures of Wormholes in Dark Matter Halos
Abdullah Guvendi, Omar Mustafa, Semra Gurtas Dogan +2
We identify scalar-wave signatures of massless fields propagating in static, spherically symmetric wormholes embedded within realistic dark matter halos. Starting from a general li…
