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
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
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 HR
Hugh, Hannah, & Andrew discuss a handful of interesting recent exoplanet papers from the past few months. Andrew delves into technosignatures and a study which looked at whether nearby extraterrestrial civilisations could detect our current levels of radio leakage, and exactly what they might be able to learn. Hannah condenses the most recent JWST exoplanet paper, on the nearby transiting super-Earth GJ486b. The beautiful spectra from JWST appear to show hints of water vapour, but
In this episode the team cover some of the latest exoplanet news stories. This month Hannah summarises the most recent exoplanetary science coming out of JWST’s early release science programs; Andrew tells us a bit about the habitability of Enceladus’s subsurface ocean, and Hugh talks about a new observation of compositional differences for planets around M-dwarfs.
