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…

Effects of Variable Mass, Disk-Like Structure, and Radiation Pressure on the Dynamics of Circular Restricted Three-Body Problem

Leonardus B. Putra, I. Nurul Huda, H. S. Ramadhan +2

In this paper, we intend to investigate the dynamics of the Circular Restricted Three-Body Problem. Here we assumed the primaries as the source of radiation and have variable mass.…

Gravitational field and lensing of a circular chiral vorton

Leonardus B. Putra, H. S. Ramadhan

We derive the metric of a circular chiral vorton in the weak field limit. The object is self-supporting by means of its chiral current. A conical singularity with deficit angle, id…
