Cahill, Hameetman Auditorium
Sounds of the Stars: Imaging Star Guts with Cosmic Music
Jim Fuller, Assistant Professor, Department of Astronomy, Caltech,
  • Public Event

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.

About the Series

Stargazing Lectures are free lectures at a public level followed by a Q&A panel and guided stargazing with telescopes (weather permitting). All events are held at the Cahill Center for Astronomy and Astrophysics at Caltech. No reservations are needed. Lectures are 30 minutes; stargazing and panel Q&A last 90 minutes. Stay only as long as you want.

Stargazing is only possible with clear skies, but the lecture and panel Q&A takes place regardless of weather.
