Differential rotation of short-lived solar filaments [PDF]
Solar Physics, 1977 We have measured the rotation rate of short-lived solar filaments as a function of their latitude. The resulting rotation curve appears to be somewhat flatter than the corresponding curve for long-lived filaments.

Solar Interior Rotation and its Variation
Living Reviews in Solar Physics, 2009 This article surveys the development of observational understanding of the interior rotation of the Sun and its temporal variation over approximately forty years, starting with the 1960s attempts to determine the solar core rotation from oblateness and ...

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 ...

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 ...

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.

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.

Differential rotation of Kepler-71 via transit photometry mapping of faculae and starspots [PDF]
, 2019 Knowledge of dynamo evolution in solar-type stars is limited by the difficulty of using active region monitoring to measure stellar differential rotation, a key probe of stellar dynamo physics.

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.

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.
