Structural Tilting and Depth-dependent Behavior of Equatorial Rossby Waves

The Astrophysical Journal
Over the past decade, solar equatorial Rossby waves have been unambiguously identified and are considered potential diagnostics of solar interior dynamics.

Full Waveform Inversion for Time-Distance Helioseismology

, 2014
Inferring interior properties of the Sun from photospheric measurements of the seismic wavefield constitutes the helioseismic inverse problem. Deviations in seismic measurements (such as wave travel times) from their fiducial values estimated for a given

Anisotropic Magnetized Asteroseismic Waves

The Astrophysical Journal
We solve for waves in a polytropic, stratified plasma with a spatially varying background magnetic field that points along the horizontal x -direction, and with gravity that is directed along the vertical z -direction.

A mixed solar core, solar neutrinos and helioseismology

, 1998
We consider a wide class of solar models with mixed core. Most of these models can be excluded as the sound speed profile that they predict is in sharp disagreement with helioseismic constraints.

Characterizing the Observational Properties of the Sun’s High-latitude m = 1 Inertial Mode

The Astrophysical Journal
Low- m inertial modes have been recently discovered in the Sun’s high-latitude regions. In this study, we characterize the observational properties of the m = 1 mode by analyzing time–distance subsurface flow maps.

The Sun’s Dark Core: Helioseismic and Neutrino Flux Constraints on a Compact Solar Center

The Astrophysical Journal
As dark matter appears to comprise most of the Galactic mass, some of it may accumulate in the cores of stars, thereby making the Sun a laboratory for constraining various dark matter theories.
