The New Era in Helioseismology [PDF]
Symposium - International Astronomical Union, 2001 The end of the millennium marks the beginning of the third phase of helioseismology. The first phase was the establishment of the initial astronomical inferences, such as estimates of the depth of the solar convection zone and the protosolar helium abundance, obtained by comparing the seismic properties of theoretical solar models with the first wave ...

Effects of Dynamo-generated Large-scale Magnetic Fields on the Surface Gravity (f) Mode
The Astrophysical Journal LettersBy modeling the upper layers of the Sun in terms of a two-layer setup where a free surface exists within the computational domain, we numerically study the interaction between the surface gravity, or the fundamental ( f ) mode, and the magnetic fields ...

A Linear Model for Inertial Modes in a Differentially Rotating Sun
The Astrophysical JournalInertial wave modes in the Sun are of interest owing to their potential to reveal new insight into the solar interior. These predominantly retrograde-propagating modes in the solar subsurface appear to deviate from the thin-shell Rossby–Haurwitz model at

Predicting Solar Magnetic Activity from Sph and Seismic Parameters Using Random Forest Regression
The Astrophysical JournalWe investigate the potential of using the photometric magnetic proxy S _ph and seismic parameters, such as the frequency of maximum power ( ${\nu }_{{\rm{\max }}}$ ) and the large frequency separation (Δ ν ), derived from Solar and Heliospheric ...

The Astrophysical JournalWe use rotation splittings derived from very long and long time series, namely 25.2, 12.6, and 6.3 yr long, computed by S. G. Korzennik independent methodology to characterize the solar tachocline and its variation with latitude and time.

Structural Tilting and Depth-dependent Behavior of Equatorial Rossby Waves
The Astrophysical JournalOver the past decade, solar equatorial Rossby waves have been unambiguously identified and are considered potential diagnostics of solar interior dynamics.
