SUMMARY OF SEQUENCE NUMBER 500043
Title: THE X-RAY COUNTERPART OF 5 MARCH 1979
Observer: KULKARNI
Subject Category: SN, SNR, and isolated NS
Seq: 500043 ObsId: 00747
Long-term Plan bin: 29-Dec-1999
ABSTRACT
The class of soft Gamma-ray Repeater (SGR) 0525-66 remain mysterious to date. One SGR, 1806-20, has been identified with a plerionic supernova remnant, with a persistent non-thermal X-ray source. SGR 0526-66 of the 5-March-1979 burst fame has been localized to the compact supernova remnant N49 in the LMC. Our sustained campaign with ASCA and ROSAT suggests that the quiescent X-ray counterpart has a soft X-ray spectrum. This can be inferred in the framework of the magnetar (highly magnetized neutron stars) model. AXAF medium resolution spectroscopy is the key to understanding the nature of this mysterious counterpart. Additionally, ACIS imaging will enable us to search for the expected synchrotron nebula powered by either the quiescent source (as in 1806-20) or by past bright bursts.
