Astronomy Unit Seminar -- Rocky Exoplanets, Geology and White Dwarfs

4 October 2019

Time: 2:30pm
Speaker: Amy Bonsor
Venue: GO Jones 610

We live in an epoch of exoplanet discovery, yet, probing the interiors of rocky exoplanets remains tricky. White dwarfs that have accreted planetary material provide a unique means to study the composition and geology of exoplanetary systems. I will discuss the origin of these observations and how we can use them to study the differentiation of exoplanetary bodies. In our Solar System, many planetary bodies have undergone large scale melting, leading to the formation of a planetary core. Does this process of differentiation also occur in exoplanetary systems?
