Cool Stars 14 - Submitted Abstract # 398 This version created on 23 October 2006 Observing YSO Outflows with LGSAO: Imaging Spectroscopy of a Highly Collimated Bipolar Jet from LkHa 233 Marshall Perrin, UC Berkeley James Graham, UC Berkeley Studying the acceleration and collimation of jets launched from young stars requires high resolution observations of the immediate circumstellar environments. The arrival of integral field spectroscopy with laser guide star adaptive optics on 8-10 m telescopes has now opened the door to sensitive, high resolution studies of jets from the ground. We have recently conducted exploratory observations of several young stars using Keck Observatory's new integral field spectrograph OSIRIS. We detected jets around 2 of our 4 targets, including a spectacular narrowly collimated jet around the Herbig Ae star LkHa 233. I present our observations of the structure and kinematics of this jet, and discuss the potential for LGSAO integral field spectroscopy to advance our understanding of jet properties across a wide range of stellar masses. ----------------------------------
