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,
The latest news hot off the Exocast news desk for June/July 2022, a very exciting month for exoplanet science: Hannah gives us a run-down of some of the long-awaited first images from JWST, including a spectrum from the atmosphere of WASP-96b from the NIRISS instrument showing clear water features. The team try (and fail) to contain their giddiness at the prospect of entering a new era of exoplanet astrophysics. Andrew takes to the theory literature
In this episode of Exocast the team are fortunate to be joined in the virtual studio by Dr Jennifer Burt, NASA/JPL’s Extreme Precision Radial Velocity Investigation Scientist, for an extreme discussion of the radial velocity technique for finding and characterising exoplanets. Jenn gives us a comprehensive and enthusiastic rundown of the method, US and European RV surveys, supporting current and future photometric missions with RV follow-up, and an update on new technology and instruments that
In this episode the Exocast gang are joined by veteran exoplaneteer Dr Mark Marley from NASA Ames. During a nearly hour-long discussion, we probe Mark’s experience of early exoplanet discovery and characterisation efforts in the 1990s, his work on clouds and atmospheric circulation models, ‘ice’ giants, brown dwarfs, his leadership role with the LUVOIR space telescope concept, as well as his cheerleading efforts during the Exocup.
Special guest interview with Natalia Guerrero
In the second of three mini-casts this month, Hannah, Hugh, and Andrew gather around the virtual table to discuss that weird and wonderful molecule: H2O! The importance of water to our lives is undeniable, but in this show we chat about what makes water so chemically unusual and important in the study of astrophysics, exoplanet astronomy, and astrobiology. http://media.blubrry.com/exocast/www.exocast.org/wp-content/uploads/2020/02/exocast_42_feature_water_jan2020-1.mp3Podcast: Play in new window | DownloadSubscribe: RSS
