The dance of the planets and the music of the stars
Tuesday, 25 June 2013 from 5:45 pm to 6:45 pm (AEST)
The dance of the planets and the music of the stars:
Prof Tim Bedding, Head of the School of Physics, the University of Sydney.
Tim is a world leader in the field of asteroseismology and has been a member of the Kepler Asteroseismic Science Consortium and its Steering Committee since 2009.
The Kepler space telescope was built to answer the question 'How common are planets like Earth?'
The high precision required detecting small planets like Earth also enables Kepler to see the signature of standing sound waves inside stars (stellar oscillations) caused by star quakes, which in turn enables us to probe the interiors of stars. This study of “asteroseismology” works in a similar way to the study of earthquakes in the interior of Earth.
Kepler has revolutionised the investigation of planets and stars since its launch in 2009, finding over 2000 planet candidates and detecting stellar oscillations in several thousands of stars. This information can tell us how planets and stars form and change, with broad implications for our understanding of how the Sun will grow old and the evolution of our Milky Way galaxy.
