The formation of asteroid satellites in large impacts:results from numerical simulations
Asteroids Collisional physics Impact processes Satellites general
2015/12/25
We present results of 161 numerical simulations of impacts into 100-km diameter asteroids, examining debris trajectories to search for the formation of bound satellite systems. Our simulations utilize...
Direct Large-Scale N-Body Simulations of Planetesimal Dynamics
N-body simulation planetesimals planetary formation planetary dynamics resonances
2015/12/25
We describe a new direct numerical method for simulating planetesimal dynamics in which N ～ 106 or more bodies can be evolved simultaneously in three spatial dimensions over hundreds ofdynamical times...
Potential Biases in the Detection of Planetary Systems with Large Transit Timing Variations
methods: data analysis – planetary systems – planets and satellites: detection –techniques: photometric
2011/9/29
The Transit Timing Variations (TTVs) technique provides a powerful tool to detect additional planets in transiting exoplanetary systems. In this paper we show how transiting planets with significant T...
