ABSTRACT
Context. The generation of X-rays in accreting T Tauri stars (TTS) is thought to be predominantly due to energy dissipation in mag-
netic fields, but alternative X-ray generation mechanisms have been proposed, such as heating in accretion shocks near the stellar
surface, or in shocks forming in jets.
Aims. We test models and trends discussed in the previous literature using X-ray data from the classical TTS T Tau.
