Erosion rate and previous extent of interior layered deposits on Mars revealed by obstructed landslides [PDF]
, 2014 We describe interior layered deposits on Mars that have obstructed landslides before undergoing retreat by as much as 2 km. These landslides differ from typical Martian examples in that their toe height increases by as much as 500 m in a distinctive ...

Eos, Transactions American Geophysical Union, 1985 The effective definition of a planet is a body too small to sustain nuclear reactions in its interior, but large enough that its thermal decay time is more than five billion years, the age of the solar system. By this definition, there are fifteen planets in the solar system: all the conventional planets but Pluto plus the seven large satellites.

Orbital dynamics of high area-to-mass ratio spacecraft under the influence of J2 and solar radiation pressure [PDF]
, 2011 This paper investigates the effect of planetary oblateness and solar radiation pressure on the orbit of high area-to-mass spacecraft. A planar Hamiltonian model shows the existence of equilibrium orbits with the orbit apogee pointing towards or away from

Tidally-forced turbulence in planetary interiors [PDF]
Geophysical Journal International, 2016 The turbulence generated in the liquid metal cores and subsurface oceans of planetary bodies may be due to the role of mechanical forcing through precession/nutation, libration, tidal forcing and collisions. Here, we model the response of an enclosed constant density fluid to tidal forcing by combining laboratory equatorial velocity measurements with ...

Eos, Transactions American Geophysical Union, 1971 Most publications on planetary interiors in the last 4 years have dealt with the moon, and the most popular topic has been the interpretation of lunar mascons (the nature and discovery of mascons are covered in the review ‘Selenodesy and Planetary Geodesy’ by W. M. Kaula).
