Helioseismic Properties of Dynamo Waves in the Variation of Solar Differential Rotation
The Astrophysical JournalSolar differential rotation exhibits a prominent feature: its cyclic variations over the solar cycle, referred to as zonal flows or torsional oscillations, are observed throughout the convection zone.

Progress in sunspot helioseismology
Journal of Physics: Conference Series, 2011 Local helioseismology is a set of methods that are used to study wave propagation and infer physical conditions in the solar interior. Sunspots are a particularly challenging target for local helioseismology. In this review, I will show that some new methods (magnetoconvection simulations and numerical wave propagation simulations) lead to shallow ...

Large-Scale Dynamics of the Convection Zone and Tachocline
Living Reviews in Solar Physics, 2005 The past few decades have seen dramatic progress in our understanding of solar interior dynamics, prompted by the relatively new science of helioseismology and increasingly sophisticated numerical models.

The Importance of Berry Phase in Solar Acoustic Modes
The Astrophysical Journal LettersAn analytic expression for the frequencies of standing waves in stars, applicable to any radial order n , is derived from ray-tracing equations by the mean of Wigner–Weyl calculus.
