Balmer-Dominated Shocks Revisited
Kevin Heng, Richard McCray
We present a new formalism to describe the ratios and profiles of emission lines from hydrogen in Balmer-dominated shocks. We use this model to interpret the measured widths and ra…
Evolutionary Status of SNR 1987A at the Age of Eighteen
Sangwook Park, Svetozar A. Zhekov, David N. Burrows +3
18 yr after the supernova explosion, the blast wave of SNR 1987A is entering the main body of the equatorial circumstellar material, which is causing a dramatic brightening o…
Chandra LETG Observations of Supernova Remnant 1987A
Svetozar A. Zhekov, Richard McCray, Kazimierz J. Borkowski +2
We discuss the results from deep Chandra LETG observations of the supernova remnant 1987A (SNR 1987A). We find that a distribution of shocks, spanning the same range of velocities…
Evolution of the Reverse Shock Emission from SNR 1987A
Kevin Heng, Richard McCray, Svetozar A. Zhekov +13
We present new (2004 July) G750L and G140L Space Telescope Imaging Spectrograph (STIS) data of the H-alpha and Ly-alpha emission from supernova remnant (SNR) 1987A. With the aid of…
