How will the world(s) end?
Talk by Prof. Boris Gänsicke (University of Warwick)
Given at the Instituto de Astrofísica de Canarias on June 27th, 2024 10:00 AM
Less than 30 years ago, we did not know whether planets exist outside our solar system. Fast forward to 2024, astronomers have discovered well over 5000 planets orbiting other stars similar to our Sun, including some that may have the right conditions to host life. As we learned that the formation of planets seems to go hand-in-hand with the birth of stars, we begin to wonder:
What happens to planetary systems when their host stars run out of fuel, and turn into Earth-sized white dwarfs?
Are those systems, if they exist, detectable?
What will happen to our solar system, and to the Earth?
And what are the possible implications for life?
I will discuss the late evolution of planetary systems, the observational fingerprints of planets and their debris orbiting white dwarfs, and how studying these exotic systems improves our general understanding of the formation of planets.
