Testing volume integrals of travel-time sensitivity kernels for flows
Michal Svanda, Daniel Chmurny
Context: Helioseismic inversions rely largely on sensitivity kernels, 3-D spatial functions describing how do the changes in the solar interior translate into the changes of helios…
Relation between magnetic field inclination and apparent motion of penumbral grains
Michal Sobotka, Jan Jurčák, J. Sebastián Castellanos Durán +1
Context. Bright heads of penumbral filaments, penumbral grains (PGs), show apparent horizontal motions inwards, towards the umbra, or outwards, away from the umbra. Aims. We aim to…
Exploiting solar visible-range observations by inversion techniques: from flows in the solar subsurface to a flaring atmosphere
Michal Švanda, Jan Jurčák, David Korda +1
Observations of the Sun in the visible spectral range belong to standard measurements obtained by instruments both on the ground and in the space. Nowadays, both nearly continuous…
Automatic detection of white-light flare kernels in SDO/HMI intensitygrams
L. Mravcova, M. Svanda
Solar flares with a broadband emission in the white-light range of the electromagnetic spectrum belong to most enigmatic phenomena on the Sun. The origin of the white-light emissio…
