T Tauri star
The T Tauri system has been of particular interest to astronomers because it is by no means a typical T Tauri star. The complex outflow system created by the jets is poorly understood, particularly in how it evolves over time. It is believed there are four jets, with two coming from T Tau N, and two coming from T Tau S (the jets of Sa and Sb appear to either combine, or Sb does not produce significant jets).
