Charles Le Losq presents a guest lecture on silicate melt viscosity and its role in understanding the dynamics and outgassing of volcanic systems, magma oceans, and lava planets, as part of the Geoscience of Exoplanets Series. The session includes a 15-minute break at 15:00.
The physico-chemical properties of magmas are central to our
understanding of the dynamics and outgassing of volcanic systems, magma
oceans, and deep magma bodies. The lecture discusses the case of the
lava planet K2-141 b and presents recent models of its surface state and
lava properties. Particular attention is paid to magma viscosity, a key
parameter controlling many magmatic and planetary processes. The effect
of pressure, which becomes important in deep magma oceans on
super-Earths and sub-Neptunes, is also considered.
