Feature Guests: Aaron Sigut and Carol Jones

sigutjonesDisks are ubiquitous in our universe. They are found in the spiral arms of galaxies. They are found among new and old stars, whether in the protoplanetary gas associated with stellar births or the black holes which follow many stellar deaths.

Today we have a special treat. I’m excited to be joined by both Carol Jones and Aaron Sigut here at The Star Spot for the first of a special two-part series. We’ll find out why disks are such common features of our universe, and how they figure prominently into a mysterious phenomenon known as B emission stars, which are among the hottest, most energetic and most mysterious of stellar phenomena.

Dave reports the probability of exoplanet habitability may have just increased significantly with scientists rethinking the once assumed life-preventing effect of planetary tidal locking. Then Laura explains the famous Pillars of Creation in the Eagle Nebula seem to be eroding away, and may have already vanished. Anuj shares new evidence that the asteroid which wiped out the dinosaurs was a truly global event. And has Beagle 2 been resurrected? Celine with new images from Mars that are shining light on the tragic fate of a spacecraft whose trip was no more smooth than that of its namesake.

About our Guests

Today two distinguished astronomy scholars from Western University are joining us here at The Star Spot. Dr. Carol Jones is Associate Dean of Graduate and Postdoctoral Studies in the Faculty of Science, as well as Associate Professor and Associate Dean in the Physics and Astronomy Department. Aaron Sigut is Associate Professor of Astronomy in the Physics and Astronomy Department. They both share research interests in circumstellar disks around hot stars, which we will get into in a series of conversations with both academics.
