The existence of a planet beyond 50 au and the orbital distribution of the classical Edgeworth–Kuiper-Belt objects
(Academic Press Inc Elsevier Science, 2002)
The dynamics of objects in the inner Edgeworth-Kuiper Bellt
(Springer, 2005-12)
Objects in 3:2 mean motion resonance with Neptune are protected from close encounters with Neptune by the resonance. Bodies in orbits with semi-major axis between 39.5 and about 42 AU are not protected by the resonance; ...
The edge of the Kuiper belt: the Planet X scenario
(Elsevier, 2004-12)
Our goal is to determine whether or not the observed sudden termination of the Edgeworth–Kuiper belt can be the result of perturbations from a hypothetical planet. We investigate the effects that such an object would produce ...
Sculpting the outer Edgeworth-Kuiper belt: stellar encounter followed by planetary perturbations
(Academic Press Inc Elsevier Science, 2005-12)
We consider a close stellar fly-by as an explanation for the abrupt termination of the classical Edgeworth-Kuiper belt at around 50 AU from the Sun, and also for the high values of orbital excitation observed. By the ...
The scattered disk population as a source of Oort cloud comets: evaluation of its current and past role in populating the Oort cloud
(Academic Press Inc Elsevier Science, 2004-12)
We have integrated the orbits of the 76 scattered disk objects (SDOs), discovered through the end of 2002, plus 399 clones for 5 Gyr to study their dynamical evolution and the probability of falling in one of the following ...
On the origin of the high-perihelion scattered disk: The role of the kozai mechanism and mean motion resonances
(Springer, 2005-03)
We study the transfer process from the scattered disk (SD) to the high-perihelion scattered disk (HPSD) (defined as the population with perihelion distances q > 40 AU and semimajor axes a>50 AU) by means of two different ...
Modelling the inner debris disc of HR 8799
(2016-11-21)
In many ways, the HR 8799 planetary system strongly resembles our own. It features four giant planets and two debris belts, analogues to the Asteroid and Edgeworth-Kuiper belts. Here, we present the results of dynamical ...
Dust around NEarby Stars. The survey observational results
