AstroMcGill Episode 72 – Steve Kawaler

Steve discusses how we can learn about the insides of stars by observing their surfaces, and how the Kepler Space telescope is the perfect instrument not only for finding extrasolar planets, but also studying oscillations on the surface of stars. We also talk about how the K2 mission is allowing us to do great science after the failure of a reaction wheel ended Kepler’s primary mission.

Guest: Steve Kawaler (Iowa State University).

Hosts: Erik Madsen and Robert Archibald.

Duration: 22 minutes.

Production: Nick Adelson.

AstroMcGill Episode 28 – Aaron Parsons

Guest: Aaron Parsons  (UC, Berkeley). We talked about the PAPER experiment, which is hoping to shed light on the end of the “dark ages” of the Universe, just as the first stars and galaxies started to form.

Hosts: Ryan Lynch and Sean Griffin.

Duration: 19 minutes.

AstroMcGill Episode 25 – Christian Ott

Guest: Christian Ott (CalTech). We discussed the death of massive stars, called supernova explosions, and how we can try to understand them with computer simulations. Here is a link to the YouTube channel mentioned during the podcast: SXS Collaboration YouTube Channel.
