Probing the X-ray emission from the low mass CTTS DN Tau

High resolution Xray spectroscopy of young stellar objects clearly indicatesthat in classical TvirgulTauri stars the physical properties of the cooler Xrayemitting plasma are strongly influenced by accretion and outflow processes. Thedetailed characteristics apparently depend on stellar parameters like mass andradius; however, especially low mass stars are missing in the the existing Xraydata of young, accreting stars. The proposed observation of DN Tau will extendthe current sample into the mass regime of M dwarf precursors and intends toderive a more comprehensive picture of the premain sequence evolution of lowmass stars. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
