Abstract:

Adaptive optics systems on large 8-10 meter class observatories allow us to better study relationships between circumstellar disks and outflows from young stars at spatial resolutions corresponding to less than the scale of our own Solar System (0."1 = 14 AU at the distance of the Taurus star forming clouds). With its fine spatial sampling and moderate spectral resolution, the Near Infrared Integral Field Spectrograph (NIFS) at Gemini North Observatory is an important new tool for investigating YSO disks and outflows at high spatial resolution. We present and discuss our near-infrared adaptive optics survey of the environments of a few of the "Classic" Classical T Tauri stars, several of which have been observed for decades using many astronomical tools and wavelength regimes. Yet, the NIFS spectra reveal new information about the structure and geometry of disks and outflows in these systems. The simultaneous kinematic and spatial information provided by the integral field spectroscopy allows further investigation of how infalling, accreting material onto a YSO in turn drives mass outflows in young stars.
