Particle-Gas Dynamics in the Midplane of a Protoplanetary Nebula
Abstract In this paper, we study the stage of planetary formation during which the particulate material is still dispersed as centimeter-to-meter sized primordial aggregates. During this stage,Expand
Size-selective Concentration of Chondrules and Other Small Particles in Protoplanetary Nebula Turbulence
Size-selective concentration of particles in a weakly turbulent protoplanetary nebula may be responsible for the initial collection of chondrules and other constituents into primitive bodyExpand
Internal stresses in phobos and other triaxial bodies
The unusual dynamical behavior of Phobos, its strange appearance, and its mysterious network of grooves all make it an intriguing object. Geophysical studies, though, have been hampered by the lackExpand
Spin states and climates of eccentric exoplanets
Abstract The known extrasolar planets exhibit a wide range of orbital eccentricities e. This has a profound influence on their rotations and climates. Because of tides in their interiors, mostlyExpand
The Tethered Moon
Abstract We address the thermal history of the Earth after the Moon-forming impact, taking tidal heating and thermal blanketing by the atmosphere into account. The atmosphere sets an upper bound ofExpand
Life near the Roche limit - Behavior of ejecta from satellites close to planets
The distribution of ejecta from impact craters significantly affects the surface characters of satellites and asteroids. In order to understand better the distinctive features seen on Phobos, Deimos,Expand
Atmospheric tides and the rotation of Venus. I - Tidal theory and the balance of torques
Insolation absorbed by the surface of Venus is quickly redeposited at the bottom of the atmosphere. This periodic heating causes mass to flow away from the warm afternoon side of the planet and intoExpand
Applications of spaceborne radar laboratory data to the study of aeolian processes
Aerodynamic roughness (z0) is an important parameter in studies of sand and dust transport, as well as atmospheric circulation models. Aerodynamic roughness is a function of the size and spacing ofExpand
Abstract Simple formulae are given for the surface area, volume, center of mass, moments of inertia, and principal axes of any homogeneous polyhedron. These can easily be combined with algorithms forExpand
