DQ Tau

(young binary star system)

DQ Tau is a non-eclipsing double-line spectroscopic binary of young T-Tauri stars, each on the order of 0.65 solar masses, about 140 parsecs distant. They have a highly-eccentricity orbit that is just above 8 radii of either star at its smallest, with an orbital period of 15 days. The star system has been studied for X-ray emissions attributed to the orbit's effect on their colliding magnetospheres.
