Title: G292.0+1.8: A REMARKABLE OXYGEN-RICH SUPERNOVA REMNANT
Observer: FEIGELSON
Subject Category: SN, SNR, and isolated NS
Seq: 500013 ObsId: 00126
Long-term Plan bin: 7-Mar-2000
ABSTRACT
G292.0+1.8, one of the radio-brightest supernova remnants (SNRs) in the sky, has a shell-type exterior with a plerionic core. Optical high-velocity O- and Ne-rich filaments are seen near the center. The X-ray morphology is also composite with a large barlike structure bisecting the shell. The X-ray spectrum shows both a non-equilibrium ionized plasma with excess metal abundances expected from a 25 solar mass progenitor, and a hard power-law component likely associated with the central synchrotron nebula. This ACIS image will elucidate the spatial distribution of elemental excesses, study dynamics of the X-ray bar with Doppler shifts, and confirm the presence of a nonthermal nebula.
