Theory and observations point to the occurrence of magma ponds or oceans in the early
evolution of terrestrial planets and in many early-accreting planetesimals. The apparent …

The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

Even a cursory historical look at the development of geology reveals that the cooling of the
Earth has always been a central issue (Birch, 1965; Fourier, 1824; Holmes, 1915; Joly …

Several episodes of complete melting have probably occurred during the first stages of the
Earth's evolution. We have developed a numerical model to monitor the thermal and melt …

The Earth is a thermal engine generating the fundamental processes of geomagnetic field,
plate tectonics and volcanism. Large amounts of heat are permanently lost at the surface …

The water content of magma oceans is widely accepted as a key factor that determines
whether a terrestrial planet is habitable. Water ocean mass is determined as a result not only …

In the Solar system, short-lived radioisotopes, such as 26Al, played a crucial role during the
formation of planetary bodies by providing a significant additional source of heat. Notably …

The distribution of chemical elements in primitive meteorites (chondrites), as building blocks
of terrestrial planets, provides insight into the formation and early differentiation of Earth. The …

We compare the results of laboratory fluid dynamics experiments with theoretical models of
turbulent entrainment in two-phase buoyant plumes and thermals to estimate the amount of …

Shock-induced melting and vaporization of H2O ice during planetary impact events are
widespread phenomena. Here, we investigate the mass of shock-produced liquid water …
