Professor Yvonne Elsworth FRS
Professor Elsworth's pioneering work in establishing and maintaining an important scientific investigation into the internal structure of the Sun using helioseismic data from the autonomous Birmingham network of observatories complemented by extant data from modes of intermediate degree has permitted an unprecedented investigation into the inner core of the Sun where the nuclear reactions are taking place. This has led to the conclusion that the deficiency of solar neutrinos detected on Earth was an issue of nuclear or particle physics, not of solar modelling; it also established that the very centre of the Sun rotates no more rapidly than the convective envelope, a matter of serious dynamical concern.
Furthermore, Professor Elsworth has led her group to study solar-cycle-related variations in the Sun's convective envelope, providing important structural information to theorists investigating the solar dynamo. Her current extension to seismic studies of stars other than the Sun is already contributing to a transformation in our understanding of stellar evolution.
