Systematic simulations of FFP scattering by a star–planet pair
The increasing number of free-floating planets discovered in recent years confirms earlier theoretical predictions and leads us to believe that the possibility of such an object intruding an existing planetary...

Trojan capture by terrestrial planets
The paper is devoted to investigate the capture of asteroids by Venus, Earth and Mars into the 1:1 mean-motion resonance, especially into Trojan orbits. Current theoretical studies predict that Trojan asteroid...

Exoplanet status report: Observation, characterization and evolution of exoplanets and their host stars
After the discovery of more than 400 planets beyond our Solar System, the characterization of exoplanets as well as their host stars can be considered as one of the fastest growing fields in space science duri...

Where are the Uranus Trojans?
The area of stable motion for fictitious Trojan asteroids around Uranus’ equilateral equilibrium points is investigated with respect to the inclination of the asteroid’s orbit to determine the size of the regi...

A survey of near-mean-motion resonances between Venus and Earth
It is known since the seminal study of Laskar (1989) that the inner planetary system is chaotic with respect to its orbits and even escapes are not impossible, although in time scales of billions of years. The...

A transiting giant planet with a temperature between 250 K and 430 K
About 70 of the more than 400 known extrasolar planets transit their central star, making it possible to observe their atmospheres and determine various key parameters. The transiting extra-solar planets so fa...

Stability of Trojan planets in multi-planetary systems
Today there are more than 340 extra-solar planets in about 270 extra-solar systems confirmed. Besides the observed planets there exists also the possibility of a Trojan planet moving in the same orbit as the J...

On the Stability of the Terrestrial Planets as Models for Exosolar Planetary Systems
All results, achieved up to now, show the long term stability of our planetary system, although, especially the inner solar system is chaotic, due to some specific secular resonances. We study, by means of num...
