An efficient numerical approach to modeling the effects of particle shape on rubble-pile dynamics
Julian C. Marohnic, Joseph V. DeMartini, Derek C. Richardson +2
We present an approach for the inclusion of non-spherical constituents in high-resolution N-body discrete element method (DEM) simulations. We use aggregates composed of bonded sph…
Is the Grand Tack model compatible with the orbital distribution of main belt asteroids?
Rogerio Deienno, Rodney S. Gomes, Kevin J. Walsh +2
The Asteroid Belt is characterized by the radial mixing of bodies with different physical properties, a very low mass compared to Minimum Mass Solar Nebula expectations and has an…
Terrestrial Planet Formation from an Annulus
Kevin J. Walsh, Hal F. Levison
It has been shown that some aspects of the terrestrial planets can be explained, particularly the Earth/Mars mass ratio, when they form from a truncated disk with an outer edge nea…
Yarkovsky V-shape identification of asteroid families
Bryce T. Bolin, Marco Delbo, Alessandro Morbidelli +1
There are only a few known main belt (MB) asteroid families with ages greater than 2 Gyr (Brož et al. 2013, Spoto et al. 2015). Estimates based on the family producing collision ra…
Hektor - an exceptional D-type family among Jovian Trojans
Jakub Rozehnal, Miroslav Brož, David Nesvorný +4
In this work, we analyze Jovian Trojans in the space of suitable resonant elements and we identify clusters of possible collisional origin by two independent methods: the hierarchi…
Water Delivery and Giant Impacts in the 'Grand Tack' Scenario
David P. O'Brien, Kevin J. Walsh, Alessandro Morbidelli +2
A new model for terrestrial planet formation (Hansen 2009, Walsh et al. 2011) has explored accretion in a truncated protoplanetary disk, and found that such a configuration is able…
