Description
Tight Triple Systems (TTS) have stars in a hierarchical configuration with a third star orbiting the inner binary with a period of fewer than 1000 days. Such systems are a hub of various dynamical interactions and are important for understanding the formation and evolution of stars in multiple systems. Having a detached eclipsing binary (DEB) as one of its components allows us to obtain precise stellar and orbital parameters of these systems. Various recent discoveries have been due to space-based photometry from Kepler and TESS. We present the accurate stellar and orbital parameters of a TTS, TIC 284595199, using TESS photometry coupled with radial velocities extracted from the triple-lined (SB3) spectra from HIDES spectrograph. Using these accurate parameters we determine the evolutionary states of the stars and the dynamic interactions possible in this system.
