T-Tauri-star

Figure 2: A model of a T Tauri star with an accretion disk. The Doppler effect seen in the emission line spectra are shown below consistent with one jet projected towards us and one away. The stellar wind is powered by the rotation of the system through the poles. From page 473 of Carroll & Ostlie (1st Ed.).
