The Spectacular Deaths of Stars

ASX held our first Star Talk on September 26 at 8pm. The speaker was Dr. Chris Matzner, a University of Toronto associate professor. The talk was given in the Lash Miller building (80 St George Street) right next to McLennan Physical Labs.

Chris Matzner writes, “Although stars appear fixed in the celestial sphere, in fact they do not last forever. Our own Sun, like most stars, will burn down one day to aglowing cinder and gradually fade away. But some stars go out with a bang, lighting up the sky with their brilliant explosions. I will tour the thrilling and macabre ways stars can meet their ends, but I will also consider how stellar death enriches the Galaxy and makes the Universe fertile for life.”

Planetary Magnetism: Unlocking the Secrets of Planetary Interiors

ASX will be holding our second Star Talk on October 24 at 8pm. The speaker is Dr. Sabine Stanley, a Canada Research Chair and Associate Professor in the Department of Physics at the University of Toronto. The talk will be given in McLennan Physical Labs (60 St George Street). The room is number 103 on the first floor. This is a FREE event and open for all ages.

Sabine Stanley writes, “Many planetary bodies in our solar system have magnetic fields that we can observe with spacecraft instruments. These magnetic fields are generated deep in planetary interiors by complex motions in liquid conductors. Because these magnetic fields are observable outside of the planet, they can act as important probes of planetary interiors. In this talk I will describe what we know of planetary magnetic fields and how they have provided us with fundamental information about the structure, composition and evolution of planets.”
