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…
Discovery of Outlying, High-Velocity Oxygen-Rich Ejecta in Cassiopeia A
R. A. Fesen, M. C. Hammell, J. Morse +7
Hubble Space Telescope images of the young Galactic supernova remnant Cassiopeia A reveal a far larger population of outlying, high-velocity knots of ejecta with a broader range of…
The Three-Dimensional Circumstellar Environment of SN 1987A
Ben E. K. Sugerman, Arlin P. S. Crotts, William E. Kunkel +2
We present the detailed construction and analysis of the most complete map to date of the circumstellar environment around SN 1987A, using ground and space-based imaging from the p…
A New View of the Circumstellar Environment of SN 1987A
Ben E. K. Sugerman, Arlin P. S. Crotts, William E. Kunkel +2
We summarize the analysis of a uniform set of both previously-known and newly-discovered scattered-light echoes, detected within 30" of SN 1987A in ten years of optical imaging, an…
On the Emergence and Discovery of Hot Spots in Supernova Remnant 1987A
Stephen Lawrence, Ben Sugerman, Patrice Bouchet +3
We present the discovery of several new regions of interaction between the ejecta and equatorial circumstellar ring of SN1987A, an interaction leading to a much expanded developmen…
