The Sun is powered through different fusion processes that can be grouped in two categories: the \textit{pp}-chain and the CNO cycle. Building a theory of the balance between gravitational and radiation forces is difficult, not least because almost all of the information about the Sun can only be gathered at a surface level. [...]

The search for Electric Dipole Moment (EDM) of elementary particles is one of the hottopics in contemporary particle physics. The method to measure charged particle EDMs(proton,deutron) is to observe the time development of a polarized beam in a dedicated storagering (Storage Ring Electric Dipole Moment (srEDM)). [...]

Deep-space radiation is among the biggest hindrances to human space exploration. Therefore, radiation protection in space is a very active field of research. [...]

The size of an atomic nucleus is a fundamental observable and defined by the distribution of the neutrons and protons composing the nucleus and the respective mean-square radii. The precise investigation of the nuclear size across the chart of nuclides delivers important benchmarks for nuclear structure theory and tests our fundamental knowledge of matter. [...]
