Context. Differences have been reported between the X-ray emission of accreting and non-accreting stars. Some observations have suggested
that accretion shocks could be responsible for part of the X-ray emission in Classical T Tauri stars (CTTS).
Aims. We present high-resolution X-ray spectroscopy of nine pre-main sequence stars in order to test the proposed spectroscopic differences
between accreting and non-accreting pre-main sequence stars.
