Evidence for extinction and accretion variability in T Tauri South

We present angularly resolved spectra of T Tau North and South in the 3 mum water-ice feature and K band. Most of the water-ice absorption lies along the line of sight toward T Tau South, confirming that it is viewed through stronger extinction. A decrease in ice-band absorption toward T Tau S betwe en 1998 December and 2000 January, significant at the 2 sigma level, was as sociated with an increase in its near-IR flux. Br gamma emission is detecte d in T Tau North and South and H-2 (2.12 mum) emission toward only T Tau So uth, consistent with previous studies of infrared companions to T Tauri sta rs. Our results suggest that the near-IR variability of T Tau S is probably caused by both variations in accretion rate and variable extinction along the line of sight.
