Spatial Structure and Collisionless Electron Heating in Balmer-dominated Shocks
Matthew van Adelsberg, Kevin Heng, Richard McCray +1
Balmer-dominated shocks in supernova remnants (SNRs) produce strong hydrogen lines with a two-component profile composed of a narrow contribution from cold upstream hydrogen atoms,…
Chandra HETG Spectra of SN 1987A at 20 years
D. Dewey, S. A. Zhekov, R. McCray +1
We have undertaken deep, high-resolution observations of SN 1987A at ~20 years after its explosion with the Chandra HETG and LETG spectrometers. Here we present the HETG X-ray spec…
Shell-shocked diffusion model for the light curve of SN2006gy
Nathan Smith, Richard McCray
We explore a simple model for the high luminosity of SN 2006gy involving photon diffusion of shock-deposited thermal energy. The distinguishing property of the model is that the la…
The Transition Zone in Balmer-Dominated Shocks
Kevin Heng, Matthew van Adelsberg, Richard McCray +1
We examine the structure of the post-shock region in supernova remnants (SNRs). The ``shock transition zone'' is set up by charge transfer and ionization events between atoms and i…
High Resolution Spectroscopy of SN1987A's Rings: He I 10830 and H-alpha from the Hotspots
Nathan Smith, Richard McCray
We present the first high-dispersion spectroscopy of He I 10830 from the hotspots in the ring around SN1987A, obtained at Gemini South, spatially resolving the near and far sides o…
Chandra Observations of Supernova 1987A
Sangwook Park, David N. Burrows, Gordon P. Garmire +3
We have been monitoring Supernova (SN) 1987A with {\it Chandra X-Ray Observatory} since 1999. We present a review of previous results from our {\it Chandra} observations, and some…
