Professor Elsworth leads the HiROS group which is active in research in the areas of solar and stellar physics uses their natural oscillations as a measurement tool. Data on the Sun are collected by the international BiSON network which is funded by the Science and Technology Facilities Council. Associated research areas of interest are in instrumentation.
Yvonne Elsworth obtained a PhD from the Victoria University of Manchester in 1976 for the design and implementation of a novel form of field-widened Michelson Interferometer designed for applications to faint, extended sources like that provided by the optical emission from the neutral thermosphere. Over the next 8 years many of the ideas developed during the PhD were applied to diverse problems including the rapid fluctuations in light from cataclysmic variable stars, wave from testing for high powered lasers and also technology transfer when Perkin Elmer decided to move into the field of interferometers in the near infrared.
An appointment In 1984 to the permanent academic staff in the School of Physics and Astronomy at the University of Birmingham caused a change of direction in the research. From that time, the focus has been helioseismology and latterly asteroseismology of solar-like and red-giant stars.
