Event Type: Lecture and Stargazing
Title: Sounds of the Stars: Imaging Star Guts with Cosmic Music
Lecturer: Jim Fuller
Position: Professor
Institution:Caltech
Abstract:
What lies at the center of a star? A stellar core is surrounded by a million Earth’s worth of plasma, so we cannot see it directly. However, the immense power of a star’s radiation causes nearly all stars to pulsate, creating “star quakes” at their surfaces. These oscillations are a collection of musical notes that uniquely define each star and are determined by its internal structure, just as the sound of a musical instrument is determined by its size and shape. Join me for a cosmic symphony as we journey to the center of the Sun, Saturn, white dwarfs, red giants, and heartbeat stars.
