Abstract:
We present a deep XMM-Newton observation of DN Tau, a M0 type classical T Tauri star (CTTS) and extend the sample of young accreting stars studied with high-resolution X-ray spectroscopy to lower masses. We detect X-ray emission from magnetic activity and accretion shocks. DN Tauís X-ray properties link it to more massive and older CTTS. The strong hot corona makes DN Tau one of the X-ray brightest CTTS in its mass range, while the low mass and large radius result in a very cool accretion component and thus reduces its imprint in the observed X-ray spectrum and emission line diagnostics.
