Abstract

DQ Tau is a young low-mass spectroscopic binary, consisting of two almost equal-mass stars on a 15.8 day period surrounded by circumbinary disk. We analyzed DQ Tau's light curves obtained by Keple K2, the Spitzer Space Telescope, and ground-based facilities. W observed variability phenomena, including rotational modulation b stellar spots, energetic stellar flares, brightening events aroun periastron due to increased accretion, and short dips due to temporar circumstellar obscuration. The study on DQ Tau will help in discoverin and understanding the formation and evolution of other real-worl examples of "Tatooine-like" systems. This is especially importan like stars were born in binary or multiple systems that broke up late due to dynamical interactions
