1SWASP J093010.78+533859.5: A POSSIBLE HIERARCHICAL QUINTUPLE SYSTEM
Among quadruples or higher multiplicity stars, only a few doubly eclipsing binary systems have been discovered. They are important targets for understanding the formation and evolution of multiple stellar systems because we can obtain accurate stellar parameters from photometric and spectroscopic studies. We present the observational results of this kind …
