Astro Edge, Episode #3 (March 4, 2023): on white dwarf's losing battle

What happens if a white dwarf star gets too close to a black hole? Can we detect such events? And can we use this to discover the enigmatic intermediate mass black holes in large quantities? I will provide the answers to these questions in this third episode of my new weekly podcast Astro Edge. --------------------------------------------------------------------- Research preprint covered in this episode: 0:44 "The Search for Thermonuclear Transients from the Tidal Disruption of a White Dwarf by an Intermediate Mass Black Hole", by Sebastian Gomez and Suvi Gezari: https://arxiv.org/abs/2302.14070 (submitted on 27 Feb 2023) ---------------------------------------------------------------------- Wikipedia articles used in this episode: https://en.wikipedia.org/wiki/Black_hole https://en.wikipedia.org/wiki/Stellar... https://en.wikipedia.org/wiki/Hypernova https://en.wikipedia.org/wiki/Superma... https://en.wikipedia.org/wiki/Interme... https://en.wikipedia.org/wiki/Tidal_d... https://en.wikipedia.org/wiki/White_d... https://en.wikipedia.org/wiki/Red_giant https://en.wikipedia.org/wiki/Planeta... https://en.wikipedia.org/wiki/Zwicky_... https://en.wikipedia.org/wiki/Vera_C.... https://en.wikipedia.org/wiki/Nancy_G... ---------------------------------------------------------------------- My name is Sergey Mashchenko. I am a Canadian, with a research background in computational astrophysics. You can check out my research on my Google Scholar page: https://scholar.google.com/citations?... Every day astronomers and astrophysicists from around the world submit their newest research results to the preprint web site https://arxiv.org (around 400 preprints each week). In my weekly podcast Astro Edge I showcase interesting research preprints submitted in the preceding week. The series are aimed at people who like science and want to stay updated about the trends and discoveries in astronomy and astrophysics. ---------------------------------------------------------------------- Multimedia sources used in this video: All sources used in the Intro part are listed in the description under this video:    • Astro Edge: Intro   Mars panoramic image: produced by Curiosity rover (NASA): https://mars.nasa.gov/resources/24599...
