We present a catalogue of plasma jets in the solar corona with a temperature above 0.5 MK. The catalogue contains primary information about the event and of the parameters of the jet, based on the data obtained with the spaceborne high-precision EUV imaging telescope SDO/AIA and ground-based radio telescopes and spectrometers, including RATAN-600 (Radio telescope of the Russian Academy of...
Since the discovery of the solar corona, many attempts have been made to model its behaviour. Perhaps the most well-known attempt was made by Parker (1958) when he assumed that the quiet sun corona is in hydrodynamical balance. Nevertheless, his model has several limitations (a saddle point, non-diverging solutions, etc). Lemaire & Stegen (2016) introduced the DYN model that addressed those...
The Ca II 854.2 nm line is currently one of the most favored spectral lines for spectropolarimetric studies of the solar chromosphere. The interpretation of the line is commonly supported by sophisticated NLTE inversion codes, which look for the atmospheric stratification whose Stokes profiles best match the observed data. Several studies have employed this line to analyze oscillatory...
The ubiquity of low-amplitude decayless kink oscillations of plasma loops allows for the seismological probing of the corona on a regular basis. We analysed decayless kink oscillations in several distinct loops belonging to active region NOAA 12107 during its quiet time period. The oscillation periods were estimated with the use of the Motion Magnification technique. The lengths of the...
Whistlers can be important both for electron transport in flaring loops and for electron scattering in acceleration sites. In this talk we focus on two questions: how accelerated electrons generate whistlers in a flaring loop and how the initial electron energy spectrum is transformed due to interactions with the whistlers. It is shown that for a given non-stationary injection of nonthermal...
We study quasi-periodic oscillations of two solar filaments based on observations in 304 \AA ultraviolet line provided by SDO/AIA.
Time-distance diagrams based on the intensity maps were produced. Quasi-periodic oscillations of the transverse dimensions of the filaments with periods of 4-8 and 10- 20 minutes have been revealed. On the basis of the obtained results, the amplitude-phase...
