Exocast-53b: Interview with Elizabeth Tasker

In this episode the Exocast crew are excited to talk with expert science communicator, JAXA space scientist, and master of computer simulations, Professor Elizabeth Tasker. During the hour long discussion we talk about how Elizabeth transitioned into planetary research from a degree and PhD in galactic simulations, the journey from the UK to the US, Canada and now in Japan. Where the idea for her popular science book The Planet Factory came from and why

Exocast-51b: Interview with Mark Marley

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.

Exocast-50c: Monthly Exoplanet News

In this month’s news rundown Hugh, Hannah, and Andrew provide a summary of three interesting papers that appeared on their radar during February/March 2021: Hugh takes a look at The Chemical link between stars and their rocky planets by Vardan Adibekyan and others. Andrew summarises Lithologic Controls on Silicate Weathering Regimes of Temperate Planets by Kaustubh Hakim and team. Hannah dons a thermal raincoat to cover Water on hot rocky exoplanets by Edwin Kite and Laura

Exocast-46b: Interview with Moiya McTier

This month Hugh, Andrew, and Hannah talk to astrophysicist, folklorist, and science communicator Moiya McTier. Moiya is an NSF graduate researcher at Columbia University in New York City and works to understand exoplanets from a galactic perspective. The Exocast team talks to Moiya about work from measuring the topography on an exoplanet by the effect that mountains and other features have in transit, all the way up to how the stars in the Milky Way

Exocast-43 d: Exoplanet news

In the final of three mini-exocasts we will release this month, we cover some of the notable happenings in exoplanet science over the past month. On this episode we cover new planets from the TESS mission, a novel technique for detecting exoplanets using radio emission, and the end of the very productive KELT survey after 17 years. We also revisit K2-18b, which hit the exoplanet headlines last year after water vapour was definitively detected in

Exocast-42b: Special Guest Dr Stephen Kane

Our final bite-size episode for this month features Andrew, Hannah, and Hugh chatting with Dr Stephen Kane, Associate Professor of Planetary Astrophysics in the Departments of Earth and Planetary Sciences and Physics and Astronomy at the University of California, Riverside. Stephen tells us a little about his need to use all exoplanet detection techniques, his love for our hot and cloudy next-door neighbour Venus, and he tries to sneak two planets into our adopted exoplanet list, before settling on one

Exocast-40b: Brett Morris talks starspots & astrobiology, the #ExoCup2019 is underway, plus exoplanet news

Hugh chats with his colleague at the University of Bern Dr. Brett Morris about starspots and their effect on exoplanet detection and characterisation, his experience with an astrobiology mission right here on Earth, and he recounts an exciting day in Bern earlier this year. Andrew discusses the labels we apply to the worlds we find, and the gang debates the usefulness of the terms for exoplanet science. And Hannah reads ADS so you don’t have

Exocast-37b: Live at TESScon, an intro to planetary protection, & the month in exoplanet news

Quizmaster Hugh takes to the conference hall at the 1st TESS Science Conference (TESSCon) to test the attendees’ exoplanet knowledge! Andrew compiles a (not very) top secret report-out on planetary protection. And Hannah covers this month’s news including the detection of an exoplanet magnetic field, new planets from TESS, a Kepler-load of 350 new candidates, as well as advances in exoplanet population statistics and atmospheric characterization. http://media.blubrry.com/exocast/p/www.exocast.org/wp-content/uploads/2019/08/Exocast-37b_v1.mp3Podcast: Play in new window | DownloadSubscribe: RSS

Exocast-30b: with special guest Jessie Christiansen, plus ExoCup2018 analysis

On the 30th episode of Exocast: Andrew is joined in the virtual exocast studio by Dr Jessie Christiansen from Caltech/NExSci to talk a little about her work on exoplanet demographics, catalogs, public outreach, and citizen science. Hannah provides an overview of last month’s #exocup, giving us a run down on the stats, the winners, losers, surprises and lessons learned. Hugh takes a look at what other exoplanet news had been released over the past month.

Exocast-8b

Exocast-8b In the eighth Exocast episode: • Andrew turns his attention to the weird and wonderful worlds bringing science fiction and fact a little closer together; • Hugh covers the latest developments in the case of the enigmatic Boyajian’s Star; • Hannah reports on the month’s news in exoplanet research; • And we adopt Latham’s Planet (HD 114762 b), arguably the first exoplanet discovered, into our planet family. http://media.blubrry.com/exocast/p/www.exocast.org/wp-content/uploads/2016/12/exocast8b_v3.mp3Podcast: Play in new window | DownloadSubscribe: RSS

Exocast-6b

Exocast-6 b In the sixth exocast episode: Hugh outlines the process of turning a potential detection into a confirmed planet. Hannah gets dusty peering through atmospheric hazes, aerosols and clouds. Andrew covers the big exoplanet news of the month: the discovery of a small, rocky exoplanet orbiting our nearest stellar neighbour Proxima Centauri. Hannah adds the fascinatingly eccentric giant planet HD80606 to our motley crew of exoplanet misfits. http://media.blubrry.com/exocast/p/www.exocast.org/wp-content/uploads/2016/09/exocast_6b_v1.mp3Podcast: Play in new window | DownloadSubscribe: RSS
