Abstract: Atoms, the building blocks of all matter, hold the key to understanding the mysteries of our universe. Through atomic physics, we gain insight into the behaviour of atoms, by studying their quantum mechanical energy structures, their spectral characteristics, as well as their interactions with external sources. This knowledge enables us to create models that guide our understanding of astrophysical plasmas, where matter and photons form intricate interactions. An ongoing puzzle in astrophysics is the cosmic origin of neutron-capture nucleosynthesis, through which many elements crucial to our existence are formed. This licentiate thesis focuses on exploring atomic structure calculation methods for these elements which should prove useful in astrophysical applications. Through this work, we hope to show the intertwined nature of atomic physics and astrophysics and the importance of bridging these two fields.
