In the Nice model, the late heavy bombardment (LHB) is related to an orbital instability of giant planets which causes a fast dynamical dispersion of a transneptunian cometary disk. We study effects…
DYNAMICAL EVIDENCE FOR A LATE FORMATION OF SATURN’S MOONS

We explore the past evolution of Saturn’s moons using direct numerical integrations. We find that the past Tethys–Dione 3:2 orbital resonance predicted in standard models likely did not occur,…

We develop an evolutionary model of the long-period comet (LPC) population, starting from their birthplace in a massive trans-Neptunian disk that was dispersed by migrating giant planets. Most comets…
THE EVOLUTION OF ASTEROIDS IN THE JUMPING-JUPITER MIGRATION MODEL

In this work, we investigate the evolution of a primordial belt of asteroids, represented by a large number of massless test particles, under the gravitational effect of migrating Jovian planets in…
On the oldest asteroid families in the main belt

Asteroid families are groups of minor bodies produced by high-velocity collisions. After the initial dispersions of the parent bodies fragments, their orbits evolve because of several gravitational…
Detection of the Yarkovsky effect for C-type asteroids in the Veritas family
- V. Carruba, D. Vokrouhlick'y, D. Nesvorn'y
- Geology, Physics
- 11 May 2017
The age of a young asteroid family can be determined by tracking the orbits of family members backward in time and showing that they converge at some time in the past. Here we consider the Veritas…
The origin of long-lived asteroids in the 2:1 mean-motion resonance with Jupiter

- Physics, Geology
- 16 May 2015
The 2:1 mean-motion resonance with Jupiter harbours two distinct groups of asteroids. The short-lived population is known to be a transient group sustained in steady state by the Yarkovsky semimajor…
Constraints on the original ejection velocity fields of asteroid families
- V. Carruba, D. Nesvorn'y
- Physics, Geology
- 14 February 2016
Asteroid families form as a result of large-scale collisions among main belt asteroids. The orbital distribution of fragments after a family-forming impact could inform us about their ejection…
Did the Hilda collisional family form during the late heavy bombardment
- M. Brovz, D. Vokrouhlick'y, A. Morbidelli, D. Nesvorn'y, W. Bottke
- Geology, Physics
- 1 July 2011
We model the long-term evolution of the Hilda collisional family located in the 3/2 mean-motion resonance with Jupiter. Its eccentricity distribution evolves mostly due to the Yarkovsky/YORP effect…
