Grand Minima in a spherical non-kinematic α2Ω mean-field dynamo model
Journal of Space Weather and Space Climate, 2020 We present a non-kinematic axisymetric α2Ω mean-field dynamo model in which the complete α-tensor and mean differential rotation profile are both extracted from a global magnetohydrodynamical simulation of solar convection producing cycling large-scale ...

Statistical hydromechanics of the solar differential rotation [PDF]
Proceedings of the National Academy of Sciences, 1982 An axisymmetric hydrodynamic model of the solar differential rotation is suggested that differs from the previous axisymmetric models (with arbitrarily given anisotropic viscosity) in the use of the hydrodynamic equations (the Friedmann-Keller equations) for the statistical second moments of the fluctuations of velocity and entropy—i.e., turbulent ...

Minuscule Corrections to Near-surface Solar Internal Rotation Using Mode Coupling
The Astrophysical Journal Supplement Series, 2023 The observed solar oscillation spectrum is influenced by internal perturbations such as flows and structural asphericities. These features induce splitting of characteristic frequencies and distort the resonant-mode eigenfunctions.

Anti‐solar differential rotation
Astronomische Nachrichten, 2004 AbstractThe differential rotation of anti‐solar type detected by observations for several stars may result from a fast meridional flow. The sufficiently intensive meridional circulation may be caused by large‐scale thermal inhomogeneities or, perhaps, by tidal forcing from a companion star.

INTERNAL-CYCLE VARIATION OF SOLAR DIFFERENTIAL ROTATION [PDF]
The Astrophysical Journal Supplement Series, 2013 The latitudinal distributions of the yearly mean rotation rates measured respectively by Suzuki in 1998 and 2012 and Pulkkinen $\&$ Tuominen in 1998 are utilized to investigate internal-cycle variation of solar differential rotation. The rotation rate at the solar Equator seems to decrease since cycle 10 onwards.

Evidence of a Quasiperiodic Global-scale Oscillation in the Near-surface Shear Layer of the Sun
The Astrophysical Journal Letters, 2023 We present evidence of hitherto undiscovered global-scale oscillations in the near-surface shear layer of the Sun. These oscillations are seen as large-scale variations of radial shear in both the zonal and meridional flows relative to their mean values.

Time-series Doppler images and surface differential rotation of the effectively-single rapidly-rotating K-giant KU Pegasi [PDF]
, 2016 According to most stellar dynamo theories, differential rotation (DR) plays a crucial role for the generation of toroidal magnetic fields. Numerical models predict surface differential rotation to be anti-solar for rapidly-rotating giant stars, i.e ...

Differential Rotation for Different-sized Sunspot Groups Early Observed by the OGAUC
The Astrophysical Journal, 2023 Solar differential rotation is an important ingredient of the solar dynamo model, not only because the solar rotation profile is one of the key inputs in a solar dynamo model, but also because it imposes constraints for the solar dynamo model.

Solar cycle-related variation in solar differential rotation and meridional flow in solar cycle 24
Earth, Planets and Space, 2020 We studied temporal variation of the differential rotation and poleward meridional circulation during solar cycle 24 using the magnetic element feature tracking technique.
