Application of Laboratory Atomic Physics to Some Significant Stellar Chemical Composition Questions
atomic physics; transition probabilities; hyperfine and isotopic substructure; stellar spectroscopy; chemical compositions
This brief review highlights some current issues in Galactic stellar nucleosynthesis, and some recent laboratory studies by the Wisconsin atomic physics group that have direct application to stellar spectroscopy to advance our understanding of the chemical evolution of our Galaxy. The relevant publication history of the lab studies are summarized, and investigations into the abundances of neutron-capture and iron-peak elements in low metallicity stars are described. Finally, new initiatives in near-infrared spectroscopy are briefly explored.
