Prashin Jethwa: "Speed Junkies: The origin and fate of the fastest stars in the Galaxy"
Universitätssternwarte
Türkenschanzstraße 17, 1180 Wien
Vortrag
Buckle up and prepare for an interstellar ride! In this talk, we’ll dive into the thrilling world of the fastest stars in the Milky Way - hypervelocity stars. These cosmic speed junkies are tearing through space at breakneck velocities, often fast enough to escape the gravitational grip of our galaxy. But where do these runaway stars come from, and what drives them to such extraordinary speeds?
We’ll explore the explosive scenarios that create them, from close encounters with the supermassive black hole at the heart of the Milky Way to the dramatic aftermath of stellar explosions. Along the way, you’ll discover how astronomers track these stellar speedsters and use them as cosmic probes to map the unseen structure of our galaxy.
Whether you’re a stargazer, a thrill-seeker, or just curious about the extremes of the universe, this talk will leave you racing to learn more about the fast and furious lives of hypervelocity stars—and what their ultimate fate reveals about the vast, dynamic cosmos we call home.
