T Tauri stars

T Cha - example of TTau star from the ASAS data

T Tauri type stars are very young (<math> <10^7 </math> y), low mass (<math> <3 M^{}_\odot </math>) pre-main sequence objects Appenzeller & Mundt 1989.


  • irregular and quasi-periodic variations
  • high amplitude (up to 5 mag)
  • may have a phase of quiescence (see figure)
  • absolute magnitude range: M_V=? to ? mag
  • typically do not require a trigger, but watch list of T Tauris would be useful
