Im letzten Seminar des Jahres spricht Gerd Steinle-Neumann zum Thema Hydrogen in Earth's core. Does it get in and what does it do?. Er präsentiert Forschungsergebnisse seiner Arbeitsgruppe am Bayerischen Geoinstitut der Universität Bayreuth, die auf Molekulardynamik-Simulationen basieren. Der Vortrag findet auf englischer Sprache statt.
Co-Host ist dieses Mal Josua Pakulla.
Das DeepDyn Seminar findet online als zoom-meeting statt. DeepDyn Mitglieder erhalten den Zuganglink automatisch vor dem Seminar. Wir bitten externe Seminargäste sich für das Seminar zu registrieren, um den Zugangslink zu erhalten.
Hydrogen in Earth's core. Does it get in and what does it do?
© Gerd Steinle-Neumann
Abstract
Light elements play an important role in the dynamics and evolution of the Earth’s core. Processes from the segregation of the core in the young Earth to the ongoing partitioning of light elements between the outer and inner core and possible exsolution from the outer core liquid determine their role in planetary structure and the geodynamo. Here I will discuss the behavior of one light element candidate, hydrogen, from its transport to the core, through its behavior at inner core crystallization (see teaser figure), to its potential role in a light element-enriched layer below the core-mantle boundary. As relevant experiments are extremely challenging, the work presented is mostly based on large-scale molecular dynamics simulations.
