Physics

Scientific paper

We propose a deep ACIS observation of the jet system of the classical T Tauri star DG Tau. DG Tau is so far unique because both its jet and counter-jet have been detected in X-rays. We will study jet structure, temperatures and proper motions of the sources and model the heating, propagation, and cooling physics of the hot plasma jets. The system orientation allows the counter-jet to be viewed through the circumstellar disk. X-ray absorption by the disk gas can thus be reliably determined and be used, together with optical information, to determine the gas-to-dust ratio in the disk. We will request radio (VLA) observations for complementary imaging, and near-IR (VLT) observing time for high-resolution spectroscopy to characterize the jet shocks and measure extinction along the jets.
