SUMMARY OF SEQUENCE NUMBER 500031
Title: A STUDY OF THE OLD SUPERNOVAE SN1993J, SN1995N, AND SN1996CB
Observer: SWARTZ
Subject Category: SN, SNR, and isolated NS
Seq: 500031 ObsId: 00735
Long-term Plan bin: 2-May-2000
ABSTRACT
We propose 50 ks ACIS-I observations of three extragalactic supernovae aged 1000-2000 days post-explosion in order to study the interaction of supernova ejecta with circumstellar matter. Each target presents unique observational opportunities: SN~1993J, whose unprecedented x-ray, radio, and optical evolution may reflect a complex binary interaction; SN~1995N, the only member of the class of peculiar Type~II events to be observed at x-ray energies at such an early evolutionary phase; and SN~1996cb, the only other SN 1993J-like Type~IIb available for x-ray study. Data will be used to probe the dynamics of the interaction region; examine the structure of the supernova ejecta and the circumstellar medium; and to study the late stages of stellar evolution.
