Modelling the emergence and evolution of the rotation-activity relation
Kieran A. Stuart, Scott G. Gregory
Main-sequence stars follow a well-defined rotation-activity relation. There are two primary regimes: saturated, where the fractional X-ray luminosity is appro…

X-ray emission from pre-main sequence stars with multipolar magnetic fields
Kieran A. Stuart, Scott G. Gregory
The large-scale magnetic fields of several pre-main sequence (PMS) stars have been observed to be simple and axisymmetric, dominated by tilted dipole and octupole components. The m…
