Exocast-82b: Exoplanet Emission and the paradigm shift of JWST with Dr Megan Weiner Mansfield
For this episode the Exocast team are joined by Dr Megan Weiner Mansfield from the University of Maryland, USA. Megan’s work focuses on the measurement of exoplanet atmospheres with a particular look at the eclipse as the planet passes behind the star and we can measure the thermal dayside of tidally locked giants. We talk about the paradigm shift that JWST has brought to the field and some really cool techniques that can be used to dive into the atmospheres of these alien worlds more.
In addition, as always we ask our guest to adopt an exoplanet into our Exocast family with Megan choosing GJ 486b – listen in to find out why!
Megan completed a PhD at the University of Chicago in Geophysical Science before being awarded a NASA Sagan Fellowship which she took to the University of Arizona and later awarded a 51 Pegasi Fellowship at Arizona State University. She is now faculty at the University of Maryland where her group works on methods of measuring exoplanet atmospheres from observations and theory.

Exocast-81b: A chat with Dr Matt Kenworthy about weird dips in light curves and the future of instrumentation
For this episode the Exocast team are joined by Dr Matthew Kenworthy from the University of Leiden, The Netherlands. Matt’s work focuses on strange transit events and the search for new ways to better process data. Matt started his career in the instrumentation lab and we dive into that transition to more remote hands-off research. We talk about his work with the assassin, sorry ASASSN, network and the search for weird dips, and then what the future of instrumentation holds for our search for planets in the universe.
In addition, as always we ask our guest to adopt an exoplanet into our Exocast family with Matt choosing PSR 1829-10 – listen in to find out why and if it exists at all!?
Matt is a British astronomer who did his PhD at the University of Cambridge after an undergrad at Oxford, he then held postdocs at Steward Observatory at the University of Arizona, and then at the University of Cincinnati then back at Steward as an instrument scientist, however he has been working and living in the Netherlands for the over a decade as a professor at the Leiden Observatory.

Exocast-80 b: Are giant planets friends or foes? With Dr Jonti Horner
We sat around our virtual studio to chat with Queensland-based astronomer Jonti Horner, who works on planetary dynamics – both within our own solar system, and around others. As well as discovering the impact of giant planet dynamics on habitable planets like earth, we also discussed the importance of aboriginal astronomy in Australia, his various media appearances, and Jonti’s namesake asteroid. Finally, Jonti adopts a special planet into our hall-of-fame list. Listen to find out more!
