Starts With A Bang #77 - Stellar Destruction Starts With A Bang podcast
-
- Science
Some stars, as they go through their life cycles, will die of natural causes. They'll burn through their fuel until they can fuse elements no longer, and then will die, becoming a white dwarf below a certain mass threshold, or experiencing a core-collapse supernova that leaves behind a neutron star, a black hole, or perhaps something even more interesting above that mass threshold. But some stars, while just going about their lives, can suffer a wildly different fate: they can be murdered by other objects in the Universe. Stellar destruction can take many forms and can give off many different unique signals, and it's only by examining a wide range of the electromagnetic spectrum, as well as other types of sources, that we can decode what's actually going on across the Universe.
I'm so pleased to welcome Dr. Yvette Cendes to the program, who specializes in radio astronomy and the behavior of exotic objects that change their behavior over time: transient signals. There's so much to explore and I hope you enjoy this fascinating 90 minute discussion right here on the Starts With A Bang podcast!
