Saving Planetary Systems: Dead Zones & Planetary Migration

The tidal interaction between a disk and a planet leads to the planet’s migration. It is widely believed that this mechanism explains the variety of orbital radii of extrasolar planets. A long-standing question regarding this mechanism is how to stop the migration before planets plunge into their central stars. In this paper, we propose a new, simple mechanism to significantly slow down planet ...

Exponential law as a more compatible model to describe orbits of planetary systems

  According to the Titus-Bode law, orbits of planets in the solar system obey a geometric progression. Many investigations have been launched to improve this law. In this paper, we apply square and exponential models to planets of solar system, moons of planets, and some extra solar systems, and compare them with each other.

Orbital Resonances in Planetary Systems

There are two main types of resonance phenomena in planetary systems involving orbital motions: (i) mean motion resonance: This is intuitively the most obvious type of resonance; it occurs when the orbital periods of two planets are close to a ratio of small integers; (ii) secular resonance: this is a commensurability of the frequencies of precession of the orientation of orbits, as described b...
