"Investigating the Atmospheres of Alien Worlds"

By Dr. Ernst DeMooij, Astrophysics Research Centre, QUB

8PM Monday 9th of March

*Please note tickets can not be refunded*



The first exoplanet around a star like our Sun was discovered almost 2.5 decades ago. Since than more than three thousand additional exoplanets have been discovered. What is even more interesting is that we have started to investigate atmospheres of these planets using telescopes both on the ground and in space. In this talk I will first show how we can find these exoplanets. In addition, I will show how we can start to study the atmospheres of these alien worlds, and what we have learned from these observations so far.





I am a lecturer within the exoplanet group at the School of Mathematics and Physics at Queen's University Belfast. I started in September 2019 following on from an assistant professor position at Dublin City University. I obtained my PhD from Leiden University on Ground-based Observations of Exoplanet Atmospheres . Following that I was a postdoctoral fellow in Prof. Jayawardhana's group at the University of Toronto, and I subsequently moved to Queen's University Belfast to take up the Michael West Fellowship.

My main research is focused on the characterisation of exoplanet atmospheres using high-resolution spectroscopy, focusing in particular on novel techniques, including Doppler Tomography . In addition, I am interested in characterising exo-ring systems using the Rossiter-McLaughlin effect. I have been studying the recent Hill Sphere transit of beta Pictoris b at high spectral resolution.


After the lecture there will be a social reception in The Lombard Innand we encourage all of you to come along for a chat.

All are welcome to attend and free food will be kindly provided by The Lombard.

Keep up to date on our Facebook and Twitter sites - links on the left.

A prize draw will be held after the lecture.
