Observatory Night: Cosmic Explosions, from Supernovae to Tidal Disruption Events
7 p.m. EDT Thursday, Oct. 14
The biggest explosions in the universe dwarf any we see on Earth. In space, we regularly witness exploding stars that can shine brighter than the rest of a galaxy as a supernova, or a black hole ripping apart a star that's visible from billions of light years away in what's called a Tidal Disruption Event (TDE). In this talk, astrophysicist Yvette Cendes will discuss how we observe cosmic explosions from Earth and learn about them, from Chinese records thousands of years ago to her modern-day observations as a radio astronomer. This will include Yvette's research on supernovae, such as the closest one ever observed to Earth -- Supernova 1987A -- and outflows from TDEs that "spaghettify" stars that wander too close to black holes.
