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 ...
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 ...
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 ...
The dynamical evolution of close-in binary systems formed by a super-Earth and its host star: Case of the Kepler-21 system
(EDP Sciences, 2020-09)
Aims. The aim of this work is to develop a formalism for the study of the secular evolution of a binary system which includes interaction due to the tides that each body imparts on the other. We also consider the influence ...
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 ...
Resonant capture and tidal evolution in circumbinary systems: Testing the case of Kepler-38
(Wiley Blackwell Publishing, Inc, 2018-07)
Circumbinary planets are thought to form far from the central binary and migrate inwards by interactions with the circumbinary disc, ultimately stopping near their present location either by a planetary trap near the disc ...
A self-consistent weak friction model for the tidal evolution of circumbinary planets
(EDP Sciences, 2019-07)
We present a self-consistent model for the tidal evolution of circumbinary planets that is easily extensible to any other three-body problem. Based on the weak-friction model, we derive expressions of the resulting forces ...
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 ...
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, ...
