The Mass and Orbital-Period Distributions of Exoplanets Accounting for the Observational Selection of the Method for Measuring Radial Velocities. A Dominant (Averaged) Structure of Planetary Systems
AbstractStatistical distributions of exoplanets obtained by both ground-based and satellite telescopes are heavily distorted by observational...

Orbital Dynamics
The concept of an orbit is fundamental to the way that any object, whether artificial or natural, moves through space. Everyone knows that a...

On the orbital inclination evolution of the current large NEOs
This work aims to discuss the temporal evolution of the current large NEOs’ orbital inclination. We applied a numerical integration method to solve...

The interplay of field-tunable strongly correlated states in a multi-orbital moiré system
The interplay of charge, spin, lattice and orbital degrees of freedom leads to a variety of emergent phenomena in strongly correlated systems. In...

Change in the Orbital Period of a Binary System Due to an Outburst in a Windy Accretion Disk
AbstractWe consider a new mechanism for the removal of angular momentum from an X-ray binary system and the change in its orbital period—the mass...

Secular evolution of co-orbital motion of two exoplanets: semi-analytical investigation
We consider a system consisting of a star and two planets in co-orbital motion. The masses of the planets are much smaller than the mass of the star....
