The Creation and Destruction of Lithium in Cool Stars is a Splinter Session at Cool Stars 22, which will occur on Monday, June 24, 2024. The session focuses on current stellar structure and evolution problems where lithium (Li) acts both as a good tracer of interior conditions, as well as an indicator of the limitations of our models of low-mass stars.
The Splinter is divided in two subthemes. Our first sub-theme concerns young stars, which vary widely in the quantities of Li on their surfaces in a way largely defying standard model predictions for Li depletion - additional physics, such as magnetic fields, starspots, accretion, exoplanets, or something else, may be responsible. The second sub-theme will move the discussion to old, evolved giants that for decades have puzzled astronomers by showing large quantities of Li on their surfaces, thus challenging our understanding of fundamental nucleosynthesis and mixing in low-mass stellar interiors, binary stellar evolution, or something else entirely.
Contributed talks are encouraged on pre-MS Li depletion, Li in young and moving groups, ongoing and upcoming surveys, stellar rotation and activity, Li evolution in the post-MS, potential sources of Li, asteroseismology, mixing, and related topics - from both observational and theoretical perspectives.
