Thanks for clarifying what I thought.  I presume the larger ones then skip T-Tauri and go straight to Main Sequence.

<p>Do all stars go from Protostar stage to T Tauri and then to Main Sequence or is T-Tauri stage only for certain stars?  If only certain stars, is that those that are less than 3 solar masses which i see mentioned?  (<a href="https://en.wikipedia.org/wiki/T_Tauri_star" rel="nofollow noreferrer">https://en.wikipedia.org/wiki/T_Tauri_star</a>)</p>

Is T Tauri a compulsory stage for stellar evolution?
