Abstract

We report the discovery of Balmer-dominated filaments along almost the complete periphery of the supernova remnant RCW 86 (also known as G 315.2-2.3 or MSH 14-63). Using the UM/CTIO Curtis Schmidt telescope, we obtained deep CCD images in the emission of Hα and [S iii, together with continuum images to remove stellar confusion. After continuum subtraction, we discovered a network of Hα filaments reaching almost completely around the remnant. Most of the newly identified filaments show no corresponding [S ii] emission, indicating that they belong to the peculiar "Balmer-dominated" class of filaments. Comparison of these Balmer filaments with existing radio and X-ray images of RCW 86 shows an overall similarity, although interesting differences are apparent upon detailed inspection. While further observations of these newly identified optical filaments may eventually provide more detailed information on the kinematics and distance to RCW 86, the distance currently remains uncertain. We argue that the shorter distance estimates of ˜1 kpc are still favored.
