Simulations of the population of Centaurs – I. The bulk statistics
Large-scale simulations of the Centaur population are carried out. The evolution of 23 328 particles based on the orbits of 32 well-known Centaurs is followed for up to 3 Myr in the forward andExpand
Simulations of the population of Centaurs – II. Individual objects
Detailed orbit integrations of clones of five Centaurs ‐ namely, 1996 AR20, 2060 Chiron, 1995 SN55, 2000 FZ53 and 2002 FY36 ‐ for durations of ∼3 Myr are presented. One of our Centaur sample startsExpand
Cratering constraints on the inner Oort cloud: steady-state models
Les observations de cometes a longues periodes et le taux moyen de production des crateres terrestres sur une periode de 600 millions d'annees sont utilises pour contraindre les parametres desExpand
OSIRIS – The Scientific Camera System Onboard Rosetta
The Optical, Spectroscopic, and Infrared Remote Imaging System OSIRIS is the scientific camera system onboard the Rosetta spacecraft (Figure 1). The advanced high performance imaging system will beExpand
Can ‘invisible’ bodies be observed in the Solar System?
MANY theories of the origin of comets predict that there are ∼ 1011 comets in the Solar System; most of them, unfortunately, at such a distance that they can never be observed. Some theories go evenExpand
Origin of sungrazers : a frequent cometary end-state
The orbits of sungrazing comets originally have inclinations near 90° and perihelion distances in the approximate range 0-2 AU. Long-term secular perturbations cause correlated changes in the orbitalExpand
The populations of comet-like bodies in the Solar system
A new classification scheme is introduced for comet-like bodies in the Solar system. It covers the traditional comets as well as the Centaurs and Edgeworth–Kuiper belt objects. At low inclinations,Expand
Centaurs from the Oort cloud and the origin of Jupiter-family comets
A numerical study of an ensemble of orbits based on observed objects in the near-Neptune high-eccentricity (NNHE) region, with perihelion distances q in the range 28 60 au being roughly an order ofExpand
