Spatially unresolved data shows that the cooling phase in solar flares can be much longer than theoretical models predict. It was not yet determined whether this is also the case for different sub-regions within the flare structure.
Two questions are in the focus of this case study: 1. Are the cooling times, which are observed separately in coronal loops and the supra-arcade fan (SAF), in...
Observational evidence shows that coronal jets can hit prominences and set them in motion. The impact leads to large-amplitude oscillations (LAOs) in the prominence. We attempt to understand this process via 2.5D MHD numerical experiments. The jets are generated in a sheared magnetic arcade above a parasitic bipolar region located in one of the footpoints of the filament channel (FC)...
The Metis coronagraph is one of the remote sensing instruments of the Solar Orbiter mission launched on February 10, 2020. Metis is an innovative externally occulted coronagraph designed to observe the solar corona in an annular field of view from 1.6deg to 3deg simultaneously for the first time in the broadband linearly polarised visible light and in the narrow-band HI 121.6 nm (Lyα).

Coronal streamers are long lived structures of the solar corona, and are very important source of slow solar wind. We have analyzed few dozen of coronal streamers observed by AIA/SDO, from solar activity maximum to minimum. For each streamers we applied a Differential Emission Measure method to obtain both a temperature distribution and a value of average temperature as well as it’s change...
In this work we use realistic three-dimensional (3D) radiative-MHD simulations of the chromosphere to model distribution of radio brightness over the solar disk and radio radius at millimeter wavelengths. We compare modeled center-to-limb variations with the observed behavior derived from diverse historical measurements as well as from recent observations. Our results show that the model...
High-resolution spectropolarimetric ground-based observations, complemented with data from the space instruments, allow us to investigate the photospheric magnetic and velocity properties of sunspot penumbra during the formation and decay phases. The observed penumbral formation occurs only on one side of the studied region. This preferential location appears to be due to the absence of an...
