Tidal Evolution of Close-in Extrasolar Planets
The distribution of eccentricitieseofextrasolarplanetswithsemimajor axesa > 0:2 AU isveryuniform,andvalues for e are relatively large, averaging 0.3 and broadly distributed up to near 1. For a < 0:2Expand

Velocity Distributions among Colliding Asteroids
Abstract The probability distribution for impact velocities between two given asteroids is wide, non-Gaussian, and often contains spikes according to our new method of analysis in which each possibleExpand

Tectonic Processes on Europa: Tidal Stresses, Mechanical Response, and Visible Features
Abstract Europa's orbital eccentricity, driven by the resonance with Io and Ganymede, results in “diurnal” tides (3.5-day period) and possibly in nonsynchronous rotation. Both diurnal variation andExpand

Collisional history of asteroids: Evidence from Vesta and the Hirayama families
Abstract Collisional evolution studies of asteroids indicate that the initial asteroid population at the time mean collisional velocities were pumped up to ∼5 km/sec was only modestly larger than itExpand

Planetesimals to planets: Numerical simulation of collisional evolution
A simulation of collisional and gravitational interaction in the early solar system generates planets ∼500 km in diameter from an initial swarm of kilometer-sized planetesimals, such as might haveExpand

Tidal Heating of Extrasolar Planets
Extrasolar planets close to their host stars have likely undergone significant tidal evolution since the time of their formation. Tides probably dominated their orbital evolution once the dust andExpand

Tidal Evolution of Close-in Extra-Solar Planets
The distribution of eccentricities e of extra-solar planets with semi-major axes a > 0.2 AU is very uniform, and values for e are generally large. For a < 0.2 AU, eccentricities are much smallerExpand

The distribution of the orbits of close-in exoplanets shows evidence for ongoing removal and destruction by tides. Tides raised on a planet's host star cause the planet's orbit to decay, even afterExpand

The global effects of impact-induced seismic activity on fractured asteroid surface morphology
Abstract Impact-induced seismic vibrations have long been suspected of being an important surface modification process on small satellites and asteroids. In this study, we use a series of linkedExpand

Strike-slip faults on Europa: Global shear patterns driven by tidal stress
Abstract Diurnal tides due to orbital eccentricity may drive strike–slip motion on Europa through a process of “walking” in which faults open and close out of phase with alternate right- andExpand
