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

Oct 21 2024 40 mins  
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) i

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

Sep 05 2024 46 mins  
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

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

Aug 05 2024 41 mins  
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 Sc

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

Jul 08 2024 40 mins  
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-

Exocast-71c: Exoplanet News & the 100th episode

Dec 06 2023 32 mins  
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 an

Exocast-71b: Do All Planets Orbit Stars?

Nov 13 2023 36 mins  
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 conside

Exocast-70c: Exoplanet news

Oct 15 2023 41 mins  
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 domin

Exocast-70b: Dr. Max Günther talks transits, CHEOPS & chemistry in zero-g

Oct 02 2023 48 mins  
This month the exocast team chat to exoplanetary astronomer Dr Maximillian Guenther. We talk about finding transiting exoplanets with TESS & NGTS, bright flares from M-dwarf stars, open-source transit modelling, chemical mixing experiments in zero-g aboard the vomit comet, connections between science and art, and his role as project scientist of the ESA CHEOPS mission. And, of cour

Exocast-69b: Surviving Scientific Conferences

Aug 16 2023 46 mins  
In this episode Andrew, Hannah, and Hugh discuss the art and science of organising, and attending, scientific conferences, with a particular focus on the recent Exoclimes VI meeting held in Exeter, UK, organised by Hannah and others in the exoplanet community. These meetings are crucial for the dissemination and communication of new results among the community and further afield, b

Exocast-68c: Latest Exoplanet News

Jul 26 2023 35 mins  
Hugh, Hannah, & Andrew discuss a handful of interesting recent exoplanet papers from the past few months. We chat all things Exoclimes VI held in Exeter in June 2023, new discoveries, exciting atmospheres, and haze formation. Hugh highlights a new discovery of “A temperate Earth-sized planet [LP 791-18 d] with tidal heating transiting an M6 star” by Peterson et al. Hannah dives
