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.

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.

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.

Influence of projection effects on the observed differential rotation rate in the UV corona
Journal of Advanced Research, 2013 Following previous investigations by Giordano and Mancuso [1] and Mancuso and Giordano [2,3] on the differential rotation of the solar corona as obtained through the analysis of the intensity time series of the O VI 1032 Å spectral line observed by the ...

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.

Exploring the Temporal Variation of the Solar Quadrupole Moment J 2
The Astrophysical Journal, 2023 Recently, Rozelot & Eren pointed out that the first solar gravitational moment ( J _2 ) might exhibit a temporal variation. The suggested explanation is through the temporal variation of the solar rotation with latitude.

Magnetic fields and differential rotation on the pre-main sequence – II. the early-G star HD 141943 – coronal magnetic field, Hα emission and differential rotation [PDF]
, 2011 Spectropolarimetric observations of the pre-main sequence early-G star HD 141943 were made at three observing epochs (2007, 2009 and 2010). The observations were made using the 3.9-m Anglo-Australian Telescope with the UCLES echelle spectrograph and the ...

Transition from anti-solar to solar-like differential rotation: Dependence on Prandtl number
, 2022 (abridged) Context: Late-type stars such as the Sun rotate differentially due to the interaction of turbulent convection and rotation. Aims: The aim of the study is to investigate the effects of the thermal Prandtl number on the transition from anti ...
