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.
In this round-up of the month’s notable exoplanetary exploits, we cover all the headlines including: Proxima c (not) being directly imaged with Sphere – WASP-4b’s accelerating orbit – two new but very different sub-Saturn-mass planets – windspeed measurements on Brown Dwarfs – plus the influence of Gin & Vampires on exoplanets (from a couple of results very early this month). Also this month, check out our chat with Dr Sarah Casewell; and a discussion of
This month Hannah, Hugh, and Andrew chat with Dr Sarah Casewell about her work on irradiated brown dwarfs. Sarah is an Earnest Rutherford Fellow at the University of Leicester where she has spent her career since undergrad. We chat all things brown dwarfs and what makes the irradiated ones so special to study. Sarah also shares her journey in academia from PhD, to postdoc, manager, and now fellow, all while becoming a mum (twice). We
Exocast-38b: Exoclimes V voxbox, NASA’s Flagship mission concepts, and exoplanet news including water in the atmosphere of K2-18b
In the 13th episode of Exocast Hugh talks about planets in binary systems – are two stars better than one? Hannah discussed the importance of brown dwarfs as the intermediary between planets and stars. Andrew takes us through the latest in exoplanetary news, including the newest discoveries, investigations, and notable events in exoplanets this month. and Hannah adopts WASP-12b with it’s ruby clouds into our extreme family of exoplanets. http://media.blubrry.com/exocast/www.exocast.org/wp-content/uploads/2017/04/Exocast-13b_v1.mp3Podcast: Play in new window | DownloadSubscribe:
