Towards understanding how surface life can affect interior geological processes: a non-equilibrium thermodynamics approach [PDF]
, 2011 Life has significantly altered the Earth’s atmosphere, oceans and crust. To what extent has it also affected interior geological processes? To address this question, three models of geological processes are formulated: mantle convection, continental ...

A remnant planetary core in the hot-Neptune desert [PDF]
, 2020 © 2020, The Author(s), under exclusive licence to Springer Nature Limited. The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of ...

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.

Orbit design for future SpaceChip swarm missions in a planetary atmosphere
, 2012 The effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design equatorial long-lived orbits about the oblate Earth.

Probing the Rock Mass Fraction and Transport Efficiency inside Uranus Using 40Ar Measurements
The Planetary Science JournalThe bulk of Uranus consists of a rock–ice core, but the relative proportions of rock and ice are unknown. Radioactive decay of potassium in the silicates produces ^40 Ar.

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
