    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 herRead more

    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 discussesRead more

    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,Read more

    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 HannahRead more

    Exocast-72b: Directly Imaging Exoplanetary Motion with Dr Jason Wang

    The Exocast team return from a short hiatus to be joined on this show by Dr Jason Wang from Northwestern University in Illinois. Jason is a direct imager, and gives us a quick overview of how we are able to find and characterise planets through direct imaging, as well as discussing the Gemini Planet Imager, 51 Eridani b, KPIC, VLT’s Gravity, and the making of the well-known, jaw-dropping animation of the planetary system around HRRead more

    Exocast-71c: exoplanet news and the 100th episode

    In this most excellent 100th episode of Exocast from the team we bring you the latest in exoplanet research and news. Hannah and Andrew cover news from the TRAPPIST system. Hannah will dive into the JWST results that have come out about this very famous system of seven Earth-sized rocky planets. Two papers look to the mid-infrared to measure the light directly from the planets b and c in emission – finding that they likelyRead more

    Exocast-71b: Do All Planets Orbit Stars?

    In this episode, Hannah, Hugh, and Andrew ask the question: Do all planets orbit stars?  Even though the vast majority of planets found so far are bound to a star, there have been detections of planetary-mass objects floating alone through space. Are these planets? How do these objects form, and how can we detect them? Is it possible that these free-floating objects could be considered ‘habitable’? The exocast gang tackle these tricky topics and otherRead more

    Exocast-70c: Exoplanet news

    Hugh, Hannah, & Andrew discuss a handful of interesting recent exoplanet papers from the past few months. We chat about the news coverage of K2-18b and the claims of biomarkers in that atmosphere, new discoveries, exciting atmospheres, and haze formation. Hannah dives into the controversy of K2-18b and the announcement of DMS (a biomarker on Earth) detection amongst a methane dominated spectrum “Carbon-bearing Molecules in a Possible Hycean Atmosphere” by Madhusudhan et al.. The teamRead more
