Interactive evolution of multiple water-ice reservoirs on Mars: Insights from hydrogen isotope compositions
Mars water ice isotope atmospheric escape
2017/4/10
Remote sensing data from orbiter missions have proposed that ground ice may currently exist on Mars, although the
volume is still uncertain. Recent analyses of Martian meteorites have suggested that ...
COUPLED SPIN AND SHAPE EVOLUTION OF SMALL RUBBLE-PILE ASTEROIDS:SELF-LIMITATION OF THE YORP EFFECT
methods numerical–minor planets,asteroids general
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 ...

2015/12/25
Space weathering is the generic term used for processes that modify the optical properties of surfaces of atmosphereless rocky bodies under exposure to the space environment. The general agreement abo...

2015/12/25
We present results from direct N-body simulations of collisions between gravitational aggregates of varying size as part of a study to parameterize planetesimal growth in the Solar System. We find tha...
