Spectral Imaging of T Tauri Star Microjets
Abstract
We present integral field spectroscopy at adaptive optics spatial resolution (<0."1) of young stars obtained using NIFS at the Gemini North observatory. Transitions of molecular hydrogen and forbidden [Fe II] detected in emission in these data are of particular interest in the study of circumstellar disks and microjets in young stellar objects. Spatial resolution of emission line structures allows for the study of gas morphologies, the spectral resolution of NIFS permits characterization of gas kinematics in outflows, and the detection of multiple transitions of H2 and [Fe II] in the IFU data make it possible to construct spatially resolved maps of physical properties of the emitting gas, (e.g., extinction, H2 excitation temperatures, electron temperatures/densities). This study highlights the sensitivity of adaptive optics fed integral field spectroscopy for revealing previously unknown characteristics of disks and outflows in the inner 200 AU environments of bright T Tauri stars.
