Thermal convection is the dominant mechanism of energy transport in the outer envelope of
the Sun (one-third by radius). It drives global fluid circulations and magnetic fields observed …

Context. Local helioseismology has so far relied on semi-analytical methods to compute the
spatial sensitivity of wave travel times to perturbations in the solar interior. These methods …

Inversions for local helioseismology are an important and necessary step for obtaining three-
dimensional maps of various physical quantities in the solar interior. Frequently, the full …

As large-distance rays (say, 10–24°) approach the solar surface approximately vertically,
travel times measured from surface pairs for these large separations are mostly sensitive to …

Aims. For the first time, the motion of granules (solar plasma on the surface on scales larger
than 2.5 Mm) has been followed over the entire visible surface of the Sun, using SDO/HMI …

We extend an existing Born approximation method for calculating the linear sensitivity of
helioseismic travel times to flows from Cartesian to spherical geometry. This development is …

Abstract Recently, Duvall and Hanasoge (Solar Phys. 287, 71, 2013) found that large-
distance separation [Δ] travel-time differences from a center to an annulus [δt oi] implied a …

We compare measurements of horizontal flows on the surface of the Sun using helioseismic
time–distance inversions and coherent structure tracking of solar granules. Tracking …

This chapter brings together two of the prominent features of our star the Sun: its well‐
developed p‐mode spectrum of global oscillations excited by near‐surface convection, and …
