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 ...

The Shape of the Solar Tachocline
The Astrophysical JournalEarly helioseismic results have shown that the tachocline has a prolate shape. However, the models used in those studies constrained the tachocline to be either prolate or oblate.

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 ...

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.

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 ...

Solving the forward problem of helioseismology in the frequency domain [PDF]
, 2015 International audienceSolar acoustic waves are continuously excited by turbulent convection (a random process). The forward problem of local helioseismology was specified at the Waves 2013 conference: computing the cross-covariance of the wave field ...
