The SN 1006 Remnant: Optical Proper Motions, Deep Imaging, Distance, and Brightness at Maximum

  title={The SN 1006 Remnant: Optical Proper Motions, Deep Imaging, Distance, and Brightness at Maximum},
  author={P. Frank Winkler and Gaurav Gupta and Knox S. Long},
  journal={The Astrophysical Journal},
We report the first measurement of proper motions in the SN 1006 remnant (G327.6+14.6) based entirely on digital images. CCD images from three epochs spanning a period of 11 yr are used: 1987 from Las Campanas and 1991 and 1998 from Cerro Tololo Inter-American Observatory. The filaments in SN 1006 are nonradiative, appearing only in the Balmer lines of hydrogen. Delicate filaments—probably thin sheets seen in projection—delineate the shock front along the northwestern rim of the remnant. We use… Expand

Abstract Optical and UV emission from SN 1006 is observed on the periphery of the SNR, particularly in the NW, and arises as material from interstellar gas is ionized behind the shock front. TheExpand
Numerically investigating the morphology of the supernova remnant SN 1006 in the ambient medium with a density discontinuity
Multiband observations on the type Ia supernova remnant SN 1006 indicate peculiar properties in its morphologies of emission in the radio, optical and X-ray bands. In the hard X-rays, the remnant isExpand
