One-sided arc averaging geometries in time-distance local helioseismology
David Korda, Michal Švanda, Thierry Roudier
The study of solar oscillations (helioseismology) has been a very successful method of researching the Sun. Helioseismology teaches us about the structure and mean properties of th…

Photospheric downflows observed with SDO/HMI, HINODE, and an MHD simulation
T. Roudier, M. Švanda, J. M. Malherbe +3
Downflows on the solar surface are suspected to play a major role in the dynamics of the convection zone. We investigate the existence of the long-lasting downflows whose effects i…

Plasma flows and sound-speed perturbations in the average supergranule
David Korda, Michal Švanda
Supergranules create a peak in the spatial spectrum of photospheric velocity features. They have some properties of convection cells but their origin is still being debated in the…
