Stability of equilibrium points in modified elliptic restricted three-body problem with various perturbation sources
M. B. Saputra, H. S. Ramadhan, Ibnu N. Huda +1
This study examines the dynamics of the third body in an elliptic restricted three-body problem (ERTBP) framework, taking into account perturbations from radiation pressure, oblate…

Orbital dynamics and spin-precession around a circular chiral vorton
S. M. Holme, H. S. Ramadhan, I. Nurul Huda +1
Vortons are of interest in high-energy physics as possible dark matter candidates and as probes of Grand Unified Theories. Using the recently derived weak-field metric for a chiral…

Gravitational lensing by non-self-intersecting vortons
Leonardus B. Putra, H. S. Ramadhan
We investigate the gravitational lensing signatures of vorton configurations, considering the circular vorton, the Kibble-Turok vorton, and a newly proposed class that incorporates…
