Scientific paper

Supernovae reveal the last stages of stellar evolution, create the chemical history of the Universe, energize the interstellar gas, and occupy the center of attention for the extragalactic distance scale and cosmology. HST can make unique contributions to understanding supernovae, as the SINS program has shown. Now HST is better than ever for this work: STIS is ideal for spatially-resolved observations of SN 1987A, where a rapidly developing encounter between the fast-moving debris and the stationary inner ring has just begun. Our approach for Cycle 8 is the intensive study of a few selected objects beyond SN 1987A: SN 1993J in M81, SN 1998bu, SN 1998S and a Target-of-Opportunity observation of a bright, new supernova to be discovered during Cycle 8. We aim to explore the UV emission from supernovae, exploit the spatial resolution of HST, and press the late-time observations of supernovae into uncharted territory. The SINS team provides extensive ground-based support and analytic power to create an effective observing program that uses HST to help understand the final, most violent stage of stellar evolution.
