An alternative stable solution for the Kepler-419 system, obtained with the use of a genetic algorithm
(EDP Sciences, 2018-11)
Context. The mid-Transit times of an exoplanet may be nonperiodic. The variations in the timing of the transits with respect to a single period, that is, the transit timing variations (TTVs), can sometimes be attributed ...
Primordial migration of co-orbital satellites as a mechanism for the horseshoe orbit of Janus –Epimetheus
(Wiley Blackwell Publishing, Inc, 2019-08)
We analyze the orbital motion of two natural satellites initially in co-orbital configuration with a third (guiding) satellite embedded into a circumplanetary gas disc and undergoing tidal interactions with the central ...
Cratering and age of the small Saturnian satellites
(EDP Sciences, 2019-04-25)
Context. The small (=135 km mean radius) satellites of Saturn are closely related to its rings and together they constitute a complex dynamical system where formation and destruction mechanisms compete against each other. ...
Modeling the evection resonance for trojan satellites: Application to the saturn system
(EDP Sciences, 2018-12)
The stability of satellites in the solar system is affected by the so-called evection resonance. The moons of Saturn, in particular, exhibit a complex dynamical architecture in which co-orbital configurations occur, ...
Role of gaseous giants in the dynamical evolution of terrestrial planets and water delivery in the habitable zone
(Oxford University Press, 2018-11)
In this research, we study the effects of a single giant planet on the dynamical evolution of water-rich embryos and planetesimals, located beyond the snow line of systems around Sun-like stars, in order to determine what ...
Semianalytical model for planetary resonances: Application to planets around single and binary stars
(EDP Sciences, 2021-02)
Context. Planetary resonances are a common dynamical mechanism acting on planetary systems. However, no general model for describing their properties exists, particularly for commensurabilities of any order and arbitrary ...
Formation of Solar system analogues – II: Post-gas-phase growthand water accretion in extended discs via N-body simulations
(Oxford University Press, 2018-10)
This work is the second part of a project that attempts to analyse the formation of Solar system analogues (SSAs) from the gaseous to the post-gas phase, in a self-consistently way. In the first paper (PI) we presented our ...
Ploonets: Formation, evolution, and detectability of tidally detached exomoons
(Wiley Blackwell Publishing, Inc, 2019-07)
Close-in giant planets represent the most significant evidence of planetary migration. If large exomoons form around migrating giant planets which are more stable (e.g. those in the Solar system), what happens to these ...
GJ 273: On the formation, dynamical evolution, and habitability of a planetary system hosted by an M dwarf at 3.75 parsec
(EDP Sciences, 2020-09)
Context. Planets orbiting low-mass stars such as M dwarfs are now considered a cornerstone in the search for planets with thepotential to harbour life. GJ 273 is a planetary system orbiting an M dwarf only 3.75 pc away, ...
Resonance capture and dynamics of three-planet systems
(Wiley Blackwell Publishing, Inc, 2018-06)
We present a series of dynamical maps for fictitious three-planet systems in initially circular coplanar orbits. These maps have unveiled a rich resonant structure involving two or three planets, as well as indicating ...
