AA Tauri
AA Tauri is a young star in the constellation of Taurus, located in the young Taurus-Auriga Star Forming Region, roughly at 460 light years away from the Sun. ==A possible planetary system==
In their paper of 2003, Grinin et al. invoke the possible presence of a substellar object to explain peculiar and periodic eclipses occurring to the young star every 8.3 days. They infer a mass of 20 times that of Jupiter for the perturbing object and an orbital separation of 0.08 Astronomical Units.
