An updated review on theoretical research on the role of magnetic fields in prominences is presented. It is concluded that the theory of the Hanle effect has...
Doppler-velocity Drifts Detected in a Solar Prominence
We analyzed multiline observations of a quiescent prominence from the slit spectrograph located at the Ondřejov Observatory. Dopplergrams and integrated...
First Metis Detection of the Helium D<SUB>3</SUB> Line Polarization in a Large Eruptive Prominence
Metis on board Solar Orbiter is the space coronagraph developed by an Italian-German-Czech consortium. It is capable of observing solar corona and various...
Large-amplitude Prominence Oscillations following Impact by a Coronal Jet
Observational evidence shows that coronal jets can hit prominences and set them in motion. The impact leads to large-amplitude oscillations (LAOs) in the...
Techniques involved in measurements of solar magnetic field are based on the observation and interpretation of the polarization signal in suitable Fraunhofer...
Multidimensional energy transfer by radiation in the solar atmosphere
Both linear and nonlinear analysis are used to gain a better understanding of the effects of multi-dimensional transfer of energy by radiation in spatially...
Observational Study of Large Amplitude Longitudinal Oscillations in a Solar Filament
On 20 August 2010 an energetic disturbance triggered damped large-amplitude longitudinal (LAL) oscillations in almost an entire filament. In the present work we...
On the relation between the intensities of bright features and the local background in sunspot umbrae
A photometric study of umbral bright features (umbral dots, clusters of umbral dots, bright grains of light bridges) in sunspots is presented. It is based on...
On the width distribution of penumbral filaments in sunspots
The width distribution of the penumbral filaments is estimated using white light photographs obtained with a vacuum, Newtonian type telescope. Observations were...
