KIC 9163796 - a benchmark binary for age determination
Abstract
Binary systems constitute a valuable tool in astrophysics for gaining a deeper understanding of stellar evolution and determining stellar ages. That is particularly true for the double-lined binary KIC 9163796, which has a mass ratio of almost unity but varies significantly in temperature, luminosity and Lithium abundance. This paper outlined our approach to generate a combined stellar model for it using the MESA stellar-evolution code. By combining the available observational data with the models we derived, we aimed to find the best-fitting models for both components and to extrapolate the system's age from them.
