Description

In this contribution I present my latest analysis of the orbits in the famous triple system T Tauri.  I discuss what we can deduce about the 3D structure of the system and the long-standing question whether T Tau S is in front or in the back of T Tau N.  I also describe how a circumbinary disk around T Tau Sa/Sb can explain the brightness fluctuations of T Tau Sb, because its orbital motion moved it behind the denser parts of the disk in 2016.  In the coming years, the motion of T Tau Sb will allow us to probe the near side of the circumbinary disk.
