A Linear Model for Inertial Modes in a Differentially Rotating Sun
The Astrophysical JournalInertial wave modes in the Sun are of interest owing to their potential to reveal new insight into the solar interior. These predominantly retrograde-propagating modes in the solar subsurface appear to deviate from the thin-shell Rossby–Haurwitz model at

, 2014 The rapid exponential increase in the Alfv\'en wave speed with height above the solar surface presents a serious challenge to physical modelling of the effects of magnetic fields on solar oscillations, as it introduces a significant CFL time-step ...

Predicting Solar Magnetic Activity from Sph and Seismic Parameters Using Random Forest Regression
The Astrophysical JournalWe investigate the potential of using the photometric magnetic proxy S _ph and seismic parameters, such as the frequency of maximum power ( ${\nu }_{{\rm{\max }}}$ ) and the large frequency separation (Δ ν ), derived from Solar and Heliospheric ...

Differential rotation and radiative equilibrium in the Sun: is the tachocline spreading?
, 2015 It is well known that the combination of barotropic rotation and radiative equilibrium are mutually incompatible in stars. The Sun's internal rotation is far from barotropic, however, which allows at least the theoretical possibility that the Sun's ...

Full Waveform Inversion for Time-Distance Helioseismology
, 2014 Inferring interior properties of the Sun from photospheric measurements of the seismic wavefield constitutes the helioseismic inverse problem. Deviations in seismic measurements (such as wave travel times) from their fiducial values estimated for a given

Travel Time Shifts due to Amplitude Modulation in Time-Distance Helioseismology
, 2009 Correct interpretation of acoustic travel times measured by time-distance helioseismology is essential to get an accurate understanding of the solar properties that are inferred from them. It has long been observed that sunspots suppress p-mode amplitude,
