The beam-plasma interaction plays an important role in solar radio emission. Understanding these mechanisms makes it possible to conclude about the local parameters of the solar plasma and the dynamics of various processes. A powerful, but resource-intensive tool for studying such systems is numerical particle-in-cell simulations. Usually, the infinite plasma approximation is used to describe...
Multi-scale vortex motions are ubiquitous in the solar atmosphere. They are already extensively studied by using a number of numerical (magnetohydrostatic and magnetoconvection simulations) and observational (analysis of different spectral lines) approaches. The high-resolution magnetoconvection MuRAM data has been used in this study. For the first time, full 3D photospheric intergranural...
We analyze a C-class solar flare with the microwave (MW) data from Expanded Owens Valley Solar Array (EOVSA) and the SDO/AIA data. We find that the flare is led by an erupting filament. The interesting result is that the flare produces two MW sources, which lay at loop-top region and the region above that, respectively. Moreover, the brightness temperatures of the two sources, as well as...
Decayless transverse oscillations of solar coronal loops (or decayless oscillations for short) have attracted great attention since their discovery. Coronal bright points (CBPs) are found to be constituted by small-scale loops. However, the decayless oscillations in CBPs have not been widely reported. In this study, we identified this kind of oscillations in some CBPs using 171 Å images taken...
During solar eruptions, magnetic islands carried by reconnection downflows will encounter second reconnection process when colliding with the loop top. To investigate the second reconnection of magnetic islands, we perform high-resolution 2.5-dimensional MHD simulations of an eruption current sheet (CS) under the high-Lundquist-number and low-$\beta$ coronal environment. The fast reconnection...
