The Origins and Evolution of Exoplanet Atmospheres and Oceans

3rd Annual Lobanov-Rostovsky Lecture in Planetary Geology delivered by Professor Raymond T Pierrehumbert. Atmospheres are dynamic entities, formed from the volatile substances that accrete when a planet is formed and later in its history, cooked out in the hot-high pressure interior of the planet, and exchanging with the interior through crustal processes (for planets which have a solid surface) or mixing into the deep interior (for fluid planets). Loss of atmosphere to space is also a major mec...

The Formation of Terrestrial Planets - the 2nd Lobanov-Rostovsky Lecture in Planetary Geology

Prof Alessandro Morbidelli of the Observatoire de la Cote d'Azur in Nice gives the 2nd Lobanov-Rostovsky Lecture in Planetary Geology. He talks about the formation of planets in the universe. Morbidelli uses numerical modelling and geochemical and cosmochemical analyses to explain planetary formation within our solar system. He provides a growth history of the Earth, with reference to the specific elements found in the Earth mantle, as well as insight into the composition and timing of moon form...
