| Description | We developed a consistent theory of rotation, mixing and dynamos of the sun and other stars by utilising observational data showing a remarkably close correlation between the rotation rates and stellar activities. We achieving our main objectives of developing a consistent theory of solar rotation and mixing, of constructing a consistent theory of magnetic flux transport, of modelling a dynamo for the Sun and other stars and of elucidating the evolution of solar rotation coupled with dynamo. Furthermore, we have achieved our other original objectives of applying our helioseismic experience and expertise to test and constrain understanding of stellar evolution and structure of other stars and of developing the crucially important theory of pulsations of different (e.g. fast-rotating) stars. |
| Exploitation Route | Our findings can be taken forward to make a key contribution to world-wide active research on the structure, dynamics and variability of the Sun, thereby advancing the understanding of stellar rotation and magnetism, e.g., stimulating future observational programmes. Our findings can also be used by researchers in different fields (e.g. environmental dynamics, geophysical/laboratory plasmas, etc) since the effect of rotation, large-scale shear flows, magnetic fields, mixing, etc, are also important in other systems. |
