Scientific paper

Though most low-mass pre-main-sequence stars (T Tauri stars) emit x-rays, the x-ray emission mechanism is not well constrained by existing observations. We propose high-spectral resolution HETGS/ACIS observations of the weak-line T Tauri star DoAr 21. Through temperature- and density-sensitive line ratios, and measurements of line widths, the proposed observation will provide details on the physical condition in the x-ray emitting region, helping to distinguish between models of x-ray emission from solar-type magnetic activity and models of star-disk interactions.
