Talk:T Tauri star
|WikiProject Astronomy / Astronomical objects||(Rated C-class, High-importance)|
Contraction time is about 108 only if the mass of the protostar is 1 solar mass. The text is too precise. Rursus 22:44, 16 November 2006 (UTC)
Not to mention which the statement that contraction time is 108 years for a 1 solar mass star could really do with a specific reference, as could much of the rest of the article to be honest and preferably ones that are freely available to the general public and less than 20 years old.

CTTS & WTTS
Not sure where to add this.
- Classical T-Tauri Star (CTTS)
- actively accreting matter, UV & Infared excess.
- Weak line T-Tauri Star (WTTS)
- not accreting or barely accreting matter, no UV or Infared excess.
Thanks, CarpD 4/3/07
You're right- these definitely need to be added. I suggest right before the picture "protoplanetary disks in the orion nebula" (I added a comment in the page there)
I will take a look.
- CTTS = Classical T-Tauri Star
- WTTS = Weak-line T-Tauri Star
- NTTS = Naked T-Tauri Star
- PTTS = Post T-Tauri Star
Trying to verify this, first.

This article suggests that these stars are different from the Sun in a number of ways, but Sun says that the Sun is a T Tauri star. This needs clarification by someone more qualified than me. :P 220.127.116.11 (talk) 21:44, 8 July 2009 (UTC)
- I keep encountering references to the Sun having probably gone through a T Tauri stage. Zyxwv99 (talk) 20:23, 18 March 2016 (UTC)
Please see the lithium burning talk page for a discussion about the actual reaction particles and energies involved.
