Space weather: The kinetic transport of electrons through the upper atmosphere — in English
Přednášející: Prof. Jean Lilensten, Grenoble Alpes University, IPAG, CNRS, Grenoble, France
Anotace:
The upper atmosphere is made of two different parts. The thermosphere is the neutral gas, mainly oxygen and nitrogen. The ionosphere is its ionized counterpart (ions and electrons) that is created by the entrance of electrons and radiation of solar origin into the upper atmosphere. To describe how this energy input results in ionisation, but also excitation, heating rate, and even aurora requires to solve the Boltzmann kinetic transport equation. In the talk, I will introduce briefly the space environment and then show the basics of this equation. Without entering the solver technique, I will show the outputs at Earth but also at other planets. Finally, I will show how these efforts take place in a larger frame called "space weather".

Observations of individual solar flares in 2021-2022 and their manifestation in Solar Orbiter data with STIX, EPD, Mag, SWA and ground-based radio telescopes — in English
Přednášející: Dr. Oleksiy Dudnik, Institute of Radio Astronomy of the National Academy of Sciences of Ukraine
Anotace:
The talk will be deal with the processing of data derived from the Solar Orbiter mission. Mostly a talk will be about high energy charged particles (from EPD), X-ray flares (from STIX), and a little bit about variations of magnetic components (from MAG) and solar wind parameters (from SWA). In Conclusion, I will try to formulate unsolved tasks more than achievements.
Radio diagnostics of density turbulence in the inner heliosphere — in English
Přednášející: Dr. Eduard P. Kontar, School of Physics & Astronomy, University of Glasgow, UK
Anotace:
Solar atmosphere is a turbulent magnetised plasma that is much hotter than the solar photosphere. The turbulence could be a key to understand why and how the solar corona is heated. From the dawn of radio astronomy, observations of either remote radio sources via solar atmosphere or solar sources have demonstrated that the radio waves are scattered in the solar corona. While radio wave scattering in the corona complicates radio emission analysis, it also provides unique diagnostics of the solar atmosphere. In the talk, I will discuss past and present radio observations of density turbulence in the solar atmosphere because the launch of Parker Solar Probe and Solar Orbiter spacecraft opens unique opportunities to study turbulence both in situ and remotely.

NOTE the time, already 13.00!!! Bayesian approach to β-meteoroids detected on Solar Orbiter - How fast is the cosmic dust? — in English
Přednášející: Mgr. Samuel Kočiščák, UiT The Arctic University of Norway, Tromso
Anotace:
Solar Orbiter is well equipped to detect unbound, hyperbolic dust particles streaming from the vicinity of the Sun, study of which is one of the scientific objectives of its Radio and Plasma Waves antenna instrument. Yielding tangible physical properties of the grains on a statistical basis is not straightforward. Therefore, we take the Bayesian approach, which handles hierarchical models in a very natural way. Introduction to Bayesian modelling is a vital part of the presentation, as is the application to Solar Orbiter data and interpretation of the results.

Experimental quantum opto-spin-mechanics of a single trapped ion — in English
Přednášející: Mgr. Lukáš Slodička, Ph.D., Department of Optics, Palacky University of Olomouc
Anotace:
Atomic ions trapped and laser-cooled in radio-frequency electric potentials have pioneered the experimental control of some of the most fundamental aspects of interaction of light and matter in the quantum domain. They provide an unique testbed for implementation of a precise control of both external-motional and internal-electronic states at the level of individual atoms.
We will present some of our recent experimental results focused on the experimental generation and control of nonclassical motion and nonclassical light emission from single and multiple trapped ions.
