An Unusual Triple System: CN Lyn

Triple star systems hold significant astrophysical importance, offering profound insights into stellar evolution, dynamical interactions, and mass transfer processes. Due to their complexity compared to single or binary star systems, triple systems facilitate a more comprehensive understanding of stellar processes from formation to final stages. Thanks to large photometric surveys, such as Kepler, researchers were able to detect triple systems with long periods. Also, the latest studies show that 15% of binaries have a tertiary component. Therefore, studying such objects will lead to results that benefit every aspect of stellar astrophysics. In this talk, I will present our latest study of known but not studied in detail triple star system, CN Lyn, and our findings by combining spectroscopy, photometry, and galactic dynamic techniques.
