Local Helioseismology: Three-Dimensional Imaging of the Solar Interior [PDF]

, 2010
The Sun supports a rich spectrum of internal waves that are continuously excited by turbulent convection. The Global Oscillation Network Group (GONG) network and the SOHO/MDI (Solar and Heliospheric Observatory/Michelson Doppler Imager) space instrument ...

Effects of Dynamo-generated Large-scale Magnetic Fields on the Surface Gravity (f) Mode

The Astrophysical Journal Letters
By 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 ...

Helioseismology in the 1980s and 1990s [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractOver more than twenty years, Wojtek Dziembowski and I collaborated on nearly fifty papers, which were concentrated in helioseismology through the 1980s and 1990s, but extended early into the new century. In this review, I discuss the most significant results of this collaboration and some of the underlying sociology that contributed to the ...

Solar core homology, solar neutrinos and helioseismology [PDF]

, 1995
Precise numerical standard solar models (SSMs) now agree with one another and with helioseismological observations in the convective and outer radiative zones.

Exploring the Dynamics of Near-Surface Solar Convection with Helioseismology [PDF]

, 2015
I present a new implementation of local helioseismology along with observations of near-surface solar convection made with this method. The upper 5% of the solar radius (35 Mm) is known as the Near-Surface Shear Layer (NSSL) and is characterized by ...

A Linear Model for Inertial Modes in a Differentially Rotating Sun

The Astrophysical Journal
Inertial 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 Journal
We 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 ...

Resolving the Tachocline Using Inversion of Rotational Splitting Derived from Fitting Very Long and Long Time Series

The Astrophysical Journal
We 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.
