Abstract:

～～～～～～～～～～～～～

Asteroseismology uses the natural oscillation modes of stars to study their interiors. The wonderfully precise measurements by NASA's Kepler and TESS missions are ideal data sources for the technique. These space telescopes have been monitoring the brightness of hundreds of thousands of stars, with the main goal of discovering extrasolar planets as they transit their parent stars. At the same time, observations of stellar oscillations have led to a revolution in asteroseismology. I will discuss some of the key results, including the use of gravity modes to probe the cores of red giant stars, the characterisation of stars found to host exoplanets, and the measurement of stellar ages.

Speaker:

Professor Tim Bedding obtained his BSc (Hons) in Physics and PhD in Astrophysics from the University of Sydney. After holding a fellowship at the European Southern Observatory in Germany, he returned to Sydney in 1995 and was promoted to Professor in 2007. He is a leading expert in asteroseismology, using stellar oscillations to probe the internal structure and evolution of stars. His research has made extensive use of observations from NASA's Kepler and TESS missions, with major contributions to the study of Sun-like stars and red giants. He was elected a Fellow of the Australian Academy of Science in 2020 and was awarded an ARC Laureate Fellowship in 2022. He is also a recipient of the University of Sydney's Excellence in Teaching Award.
