From solar-like to antisolar differential rotation in cool stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2013 Abstract Stellar differential rotation can be separated into two main regimes: solar-like when the equator rotates faster than the poles and antisolar when the polar regions rotate faster than the equator. We investigate the transition between these two regimes with 3D numerical simulations of rotating spherical shells.

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 ...

Solar activity and differential rotation [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractThe coronal sidereal rotation rate as a function of latitude for each year, extending from 1992 to 2001 for soft X-ray images and from 1998 - 2005 for radio images are obtained. The present analysis reveals that the equatorial rotation rate of the corona is comparable to the photosphere and the chromosphere, However, at the higher latitudes ...

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 ...
