Minuscule Corrections to Near-surface Solar Internal Rotation Using Mode Coupling

open access: yesThe 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.

Anti‐solar differential rotation

open access: yesAstronomische 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.

Evidence of a Quasiperiodic Global-scale Oscillation in the Near-surface Shear Layer of the Sun

open access: yesThe 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.

Exploring the Temporal Variation of the Solar Quadrupole Moment J 2

open access: yesThe 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.

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

open access: yesJournal 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 ...

Solar cycle-related variation in solar differential rotation and meridional flow in solar cycle 24

open access: yesEarth, Planets and Space, 2020
We studied temporal variation of the differential rotation and poleward meridional circulation during solar cycle 24 using the magnetic element feature tracking technique.

Differential Rotation for Different-sized Sunspot Groups Early Observed by the OGAUC

open access: yesThe 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.

INTERNAL-CYCLE VARIATION OF SOLAR DIFFERENTIAL ROTATION [PDF]

open access: yesThe 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.
