The Deaths and Afterlives of Massive Stars

The Deaths and Afterlives of Massive Stars Dan Milisavljevic of Purdue University The catastrophic death of a massive star, a supernova explosion, is among the most powerful and important events in the cosmos. These brilliant bursts produce not only spectacular nebulae, but also exotic remnant objects, including neutron stars, black holes, and gamma-ray bursts. They strongly shape the structure and chemistry of their host galaxies. Perhaps most significantly, the stellar debris ejected into interstellar space is chock-full of the heavy elements that make planets and life possible. Professor Milisavljevic will vividly describe the ways that supernovae critically influence our universe. Breakthrough science opportunities are becoming possible through new synergies between the Hubble Space Telescope and observing facilities sensitive to electromagnetic energy, neutrinos, and gravitational waves. Host: Dan Milisavljevic of Purdue University Recorded live on Tuesday, April 23, 2019, at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A.
