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 possible
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 < 0:2
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 and
Tidal evolution of close-in extra-solar planets
Abstract 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
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 and
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- and
Collisional Models and Scaling Laws: A New Interpretation of the Shape of the Main-Belt Asteroid Size Distribution☆
Abstract Numerical models of the collisional evolution of the main-belt asteroids lead to a new interpretation of the shape of the observed size distribution. Using recent hydrocode predictions of
