DYNAMO EFFECTS NEAR THE TRANSITION FROM SOLAR TO ANTI-SOLAR DIFFERENTIAL ROTATION [PDF]
The Astrophysical Journal, 2015 Numerical MHD simulations play increasingly important role for understanding mechanisms of stellar magnetism. We present simulations of convection and dynamos in density-stratified rotating spherical fluid shells. We employ a new 3D simulation code for the solution of a physically consistent anelastic model of the process with a minimum number of ...

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 ...

Fluids, 2023 Contemporary three-dimensional physics-based simulations of the solar convection zone disagree with observations. They feature differential rotation substantially different from the true rotation inferred by solar helioseismology and exhibit a conveyor ...

Generation of Solar-like Differential Rotation
The Astrophysical Journal, 2022 Abstract We analyze the simulation result shown in Hotta & Kusano (2021) in which the solar-like differential rotation is reproduced. The Sun is rotating differentially with the fast equator and the slow pole. It is widely thought that the thermal convection maintains the differential rotation, but recent high-resolution simulations ...

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 ...

Rotational Characteristics of the Solar Transition Region Using SDO/AIA 304 Å Images
The Astrophysical Journal, 2023 To date, the rotational characteristics of the solar transition region remain unclear. In this work, by applying the flux modulation method to the images derived from the Solar Dynamics Observatory/Atmospheric Imaging Assembly between 2011 and 2022 at ...

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 ...

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.

Activity and differential rotation of the early M dwarf Kepler-45 from transit mapping [PDF]
, 2020 Little is known of the activity and differential rotation of low luminosity, early M dwarfs from direct observation. We present the first stellar activity analysis of star-spots and faculae for the hot Jupiter hosting M1V dwarf Kepler-45 from Kepler ...
