Abstract: It is likely both intuitive and familiar that, as you walk further from a campfire, you feel less of its heat. And yet the same is not true for the great fireball in the sky: our sun. In fact, the Sun’s corona is millions of kelvin hotter than its photosphere, despite being much further away from the center of the star. From 2020 through 2021 a team of over a thousand undergraduate students at CU Boulder painstakingly analyzed the X-ray emissions of hundreds of individual solar flares in search of evidence to help resolve this mystery. We'll discuss their findings and conclusions, as well as the novel circumstances that led to this unique collaboration, and the publication of a paper with the most co-authors in the history of The Astrophysical Journal.
The Department of Physics proudly presents the Saturday Physics Series, lectures geared toward high school students and adults to highlight the exciting research and practical potential of physics.
All lectures are free and open to the public.
