Solar and Solar-Like Oscillations: Theory [PDF]

Highlights of Astronomy, 1986
AbstractSolar five-minute oscillations provide a means of testing theoretical models of the sun. By judiciously combining data from low-degree modes, properties of the central and surface regions of the sun can be inferred separately. In principle, it should be possible to draw similar inferences from other stars, once adequate data are available ...

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.

Excitation of Solar Acoustic Oscillations

Symposium - International Astronomical Union, 1997
The stochastic excitation of solar oscillations due to turbulent convection is reviewed. A number of different observational results that provide test for solar p-mode excitation theories are described. I discuss how well the stochastic excitation theory does in explaining these observations.

The Importance of Berry Phase in Solar Acoustic Modes

The Astrophysical Journal Letters
An analytic expression for the frequencies of standing waves in stars, applicable to any radial order n , is derived from ray-tracing equations by the mean of Wigner–Weyl calculus.

Major Δ14C excursions during the late glacial and early Holocene: changes in ocean ventilation or solar forcing of climate change? [PDF]

, 2003
The atmospheric 14C record during the Late Glacial and the early Holocene shows sharp increases simultaneous with cold climatic phases. These increases in the atmospheric 14C content are usually explained as the effect of reduced oceanic CO2 ventilation ...

Effect of structuring on coronal loop oscillations

, 2007
In this Thesis the theoretical understanding of oscillations in coronal structures is developed. In particular, coronal loops are modelled as magnetic slabs of plasma.
