Secular Evolution of a Two-Planet System of Three Bodies with Variable Masses

Universe
A classical three-body problem with two planets moving around a central star of variable mass on quasi-periodic orbits is considered. The bodies are assumed to attract each other according to Newton’s law of universal gravitation. The star loses its mass

Perturbation Methods in Solving the Problem of Two Bodies of Variable Masses with Application of Computer Algebra

Applied Sciences
The classical many-body problem is not integrable, so perturbation theory based on an exact solution to the two-body problem is usually applied to investigate the dynamics of planetary systems.

A chaotic behavior and stability analysis on quasi-zero stiffness vibration isolators with multi-control methodologies

Journal of Low Frequency Noise, Vibration and Active Control
A quasi-zero stiffness vibration isolator (QZSVI) is used in applications like precision instruments, aerospace, microelectronics manufacturing, and seismic isolation to protect sensitive equipment from low-frequency vibrations.
