Average solar active region: I. Intensities, velocities, and the photospheric magnetic field
M. Švanda, J. Jurčák, M. Schmassmann
Context: Solar active regions (ARs) are key manifestations of the Sun's magnetic activity, displaying diverse spatial and temporal characteristics. Their formation and evolution pl…
Flare heating of the chromosphere: Observations of flare continuum from GREGOR and IRIS
M. García-Rivas, J. Kašparová, A. Berlicki +8
Context: On 2022 May 4, an M5.7 flare erupted in the active region NOAA 13004, which was the target of a coordinated campaign between GREGOR, IRIS, Hinode, and ground-based instrum…
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…
IRIS observations of chromospheric heating by acoustic waves in solar quiet and active regions
V. Abbasvand, M. Sobotka, M. Švanda +3
Aims: To study the heating of solar chromospheric magnetic and nonmagnetic regions by acoustic and magnetoacoustic waves, the deposited acoustic-energy flux derived from observatio…
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…
