OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected to start before the end of Hilary Term to allow all future events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed on the Staff Gateway and via email to identified OxTalks users.

How big is the Martian core? What is its composition? How does it compare to Earth’s core? The Nasa-led InSight mission placed the first seismometer on the surface of Mars, collecting data for four years, allowing us to develop new answers to these important questions. In this seminar I will talk about how seismic data from Mars, together with research from mineral physics and cosmochemistry, have helped us to look deep into Mars’s core. The seminar will address how the first seismically-informed models of the whole planet were built, as well as their implications for our understanding of core composition and evolution.
