T Tauri star
A T Tauri star, also called a T Tauri variable, is a young, low-mass star still contracting toward the main sequence, named for its prototype in Taurus.
T wave
T wave: the ECG deflection representing ventricular repolarization; normally upright except in aVR and V1, positive because repolarization runs opposite to depolarization; inversion, hyperacute, or alternans patterns mark ischemia and sudden-death risk.
