Thierry Corbard, of the Côte d'Azur Observatory (France), When will we understand the Sun's core? To understand the Sun's core we need to identify gravity modes that have not yet been fully detected. Although we can guess at the nature of these g modes, more observations and instruments are needed to improve the signal to noise ratio. Once detected, we can use the fact that these modes are sensitive to dynamic structures in the Sun's core to make some predictions about its temperature and rate of rotation. We are also likely to gain some insight into neutrino physics. Jørgen Christensen
