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! Do you have a question we didn’t ask? Join in the discussion in the comments below, and find us on bluesky.

Exocast-79b: Observing odd exoplanet orbits with Dr. Malena Rice

Join the Exocast team as they chat with Dr Malena Rice an expert on planetary and exoplanetary dynamics through both theory and observation. Malena tells us about her journey into professional astronomy. Malena grew up and attended college in California before moving to the east coast for grad school in the Yale Department of Astronomy, only taking a quick one years’ break as 51 Peg fellow at MIT before returning to Yale as an Assistant Professor in 2023. We ask what the first year as a faculty member is like and how she approaches her research and outreach.

Exocast-78 b: Finding the most distant exoplanets with Dr Eamonn Kerins

This month the gang sit in with Dr Eamonn Kerins, expert in gravitational microlensing from the University of Manchester. He tells us how astronomers can find extremely distant exoplanets through the warping effect their mass has on light itself; and takes us through the past, present and future of one of the more obscure exoplanet detection methods. This includes how ESA’s Euclid mission could contribute to NASA’s Nancy Grace Roman campaign to find hundreds of new planets in the galactic bulge. We also hear about his journey through astronomy, and outreach projects including as a Green Alien at Jodrell Bank.

Exocast-77b

For this episode the Exocast team are joined by Dr Benjamin (Ben) Pope from the University of Queensland, Brisbane. Ben has worked on everything from transit light curve modelling, to direct imaging instrumentation, to using tree rings to study solar activity and we try desperately to cover it all in the episode. Ben shares with us what excites him the most about the search for exoplanets and how instrumentation developments drive or understanding of these worlds and more importantly (to some) their stars. In addition, as always we ask our guest to adopt an exoplanet into our Exocast family with Ben choosing K2-110b which holds a special significance for him and one of our Exocast hosts – listen to find out more! Ben completed a PhD in the UK at Oxford before being awarded a NASA Sagan Fellowship which he took to NYU in the USA. He is now faculty at the University of Queensland where his group works on methods of directly imaging exoplanets. Do you have a question we didn’t ask?

Exocast-76b: Exoplanet Interiors with Professor Caroline Dorn

The Exocast team are joined on this episode by exoplanetary interior investigator Professor Caroline Dorn. Caroline started her career in Earth sciences and geophysics, studying for her PhD aquifer systems at the University of Lausanne, before switching her focus to the interiors of more distant worlds in 2013 with postdoctoral fellowships at the University of Bern and Zurich. As of April 2023, Caroline is an Assistant Professor for exoplanet science at ETH Zürich, and her newly established interdisciplinary exoplanet research group at the Institute for Particle Physics and Astrophysics is also part of the Center of Origin and Prevalence of Life. Caroline outlines what we can learn about the interior structure of rocky exoplanets from mass and radius measurements, as well as how these planets may form and evolve over time and whether plate tectonics is necessary for sustaining an atmosphere and for habitability. As always, Caroline also adds another interesting exoplanet to our growing list of Adopted Planets. Do you have a question we didn’t ask?

Exocast-75b: Radial Velocity Surveys of Young Planets with Dr. Louise Nielsen

The Exocast team are joined on this episode by Dr. Louise Nielsen, a Danish astronomer who, after a batchelor’s degree at Niels Bohr Institute in Copenhagen, moved to the Geneva Observatory for a PhD focussing on radial velocity (RV) observations of exoplanets. Louise then completed postdoctoral fellowships at the University of Oxford and the European Southern Observatory (ESO) in Garching, before joining the Ludwig-Maximilians-Universität (LMU) in Munich as a staff astronomer in 2023. Louise discusses RV of young planets, follow-up of candidates found by TESS, the future of RV surveys, and she also outlines her early work with ground-based transit surveys including the now-ended WASP survey and NGTS. As is tradition, Louise also adds another interesting exoplanet to our growing list of Adopted Planets. Danish speakers should check out her astronomy podcast Stjerneklart.

Exocast-74b: Exoplanet Characterisation and HST/JWST Mission Support with Dr. Néstor Espinoza

The Exocast team are joined on this show by Dr. Néstor Espinoza from the Space Telescope Science Institute (STScI) in Baltimore, USA. Néstor is an Assistant Astronomer and Mission Scientist for Hubble and JWST at STScI, where he focusses on transiting exoplanets and their stars. He also provides support for HST and JWST as Mission Scientist for Exoplanet Science in the Instrument Division, and Néstor speaks to the Exocast gang about balancing these distinct roles, as well as his interest in developing open-source modelling and analysis tools for exoplanet science. As always, Néstor also adds an exoplanet to our growing list of Adopted Planets; this one may be familiar to regular listeners…! Do you have a question we didn’t ask?

Exocast-73b: Using Adaptive Optics to Find Exoplanets with Jules Fowler

The Exocast team are joined on this show by Jules Fowler, a NSF Graduate Research Fellow at the University of California, Santa Cruz, where they work to improve extreme adaptive optics technologies and seek the signatures of exoplanets in polarized light. Jules also shares insights gleaned from four years working as an analyst and science software engineer at the Space Telescope Science Institute (STScI), where they had the pleasure of collaborating with Exocast’s own Hannah Wakeford to discover transiting exoplanets. As always, listen to the show to find out which ‘planet’ (hint) Jules has adopted into our hall-of-fame this time… Do you have a question we didn’t ask?
