COUPLED SPIN AND SHAPE EVOLUTION OF SMALL RUBBLE-PILE ASTEROIDS:SELF-LIMITATION OF THE YORP EFFECT
methods numerical–minor planets,asteroids general
font style='font-size:12px;'>
2015/12/25
We present the first self-consistent simulations of the coupled spin-shape evolution of small gravitational aggregates under the influence of the YORP effect. Because of YORP's sensitivity to surface ...
The Brazil nut effect and its application to asteroids
methods:numerical comets:general minor planets,asteroids:general
font style='font-size:12px;'>
2015/12/25
Out of the handful of asteroids that have been imaged, some have distributions of blocks that are not easily explained. In this paper, we investigate the possibility that seismic shaking leads to the ...

2015/12/25
Numerical simulations of asteroid breakups, including both the fragmentation of the parent body and the gravitational interactions between the fragments, have allowed us to reproduce successfully the ...
Planetesimals to protoplanets–II. Effect of debris on terrestrial planet formation

font style='font-size:12px;'>
2015/12/25
In this paper, we extend our numerical method for simulating terrestrial planet formation to include dynamical friction from the unresolved debris component. In the previous work, we implemented a rub...
