Consequences of high effective Prandtl number on solar differential rotation and convective velocity [PDF]
Observations suggest that the large-scale convective velocities obtained by solar convection simulations might be over-estimated (convective conundrum).

Anti‐solar differential rotation
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.

Evidence of a Quasiperiodic Global-scale Oscillation in the Near-surface Shear Layer of the Sun
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 of Kepler-71 via transit photometry mapping of faculae and starspots [PDF]
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.

Influence of projection effects on the observed differential rotation rate in the UV corona
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 ...

Minuscule Corrections to Near-surface Solar Internal Rotation Using Mode Coupling
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 on the active sub-giant HU Virginis [PDF]
Measuring surface differential rotation (DR) on different types of stars is important when characterizing the underlying stellar dynamo. It has been suggested that anti-solar DR laws can occur when strong meridional flows exist. We aim to investigate the

Exploring the Temporal Variation of the Solar Quadrupole Moment J 2
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.
