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

Latitude-dependent Time Variations of the Solar Tachocline
The Astrophysical JournalWe have examined how the characteristics of the tachocline—i.e., the change in rotation rate δ Ω, or the “jump,” the position of the midpoint of the tachocline, r _d , and the width of the tachocline, w _d —change as a function of time at different ...

Active-region Modulation of Subsurface Meridional Flows and Magnetic Flux Transport on the Sun
The Astrophysical Journal LettersUsing time–distance helioseismology applied to 14 yr of Solar Dynamics Observatory/Helioseismic and Magnetic Imager observations spanning solar cycle 24 and the rising phase of cycle 25, we present evidence that meridional flows in the lower half of the ...

Large-Scale Dynamics of the Convection Zone and Tachocline
Living Reviews in Solar Physics, 2005 The past few decades have seen dramatic progress in our understanding of solar interior dynamics, prompted by the relatively new science of helioseismology and increasingly sophisticated numerical models.

The Iris Network For Whole Disc Helioseismology: Recent Results
, 2007 IRIS(International Research on the Interior of the sun) is the name of a worldwide network of 6 stations for whole disc Doppler shift measurements. The network has been operating since 1987 and by now a few series of a hundred days long unbroken (by day ...
