The Orion fingers: Near-IR spectral imaging of an explosive outflow.

YOUNGBLOOD A., GINSBURG A. and BALLY J.

Abstract (from CDS):

We present near-IR (1.1-2.4 µm) position-position-velocity cubes of the 500 year old Orion BN/KL explosive outflow with spatial resolution 1'' and spectral resolution 86 km/s. We construct integrated intensity maps free of continuum sources of 15 H2 and [Fe ii] lines while preserving kinematic information of individual outflow features. Included in the detected H2 lines are the 1-0 S(1) and 1-0 Q(3) transitions, allowing extinction measurements across the outflow. Additionally, we present dereddened flux ratios for over two dozen outflow features to allow for the characterization of the true excitation conditions of the BN/KL outflow. All of the ratios show the dominance of the shock excitation of the H2 emission, although some features exhibit signs of fluorescent excitation from stellar radiation or J-type shocks. We also detect tracers of the PDR/ionization front north of the Trapezium stars in [O i] and [Fe ii] and analyze other observed outflows not associated with the BN/KL outflow.
