The X-Ray-resolved Supernova Remnant S8 in the Dwarf Irregular Galaxy IC 1613

We conducted an observation of the nearby irregular galaxy IC 1613 with the Chandra X-ray Observatory using the S3 chip of the Advanced CCD Imaging Spectrometer (ACIS) with an effective exposure time of 49.9 ks. The observation primarily targeted the extensive bubble and star formation region in the northeast quadrant of the galaxy. The only known supernova remnant (SNR) in IC 1613, S8, is also the galaxy's most luminous X- ray source (L-X(0.3-8 keV) similar to 5-6 x 10(36) erg s(-1)). We resolve the SNR with Chandra and compare its nearly circular X- ray morphology with Ha and radio images. We assign an upper limit on the luminosity of any possible associated compact central object of approximate to 4 x 10(35) erg s(-1) (0.3-8 keV band) and conclude that we would detect a Crab-like pulsar but not a Cas A-like object. We infer an age for S8 of similar to 3400-5600 yr and compare it to other SNRs in the Local Group. We suggest that S8 is a young composite SNR.
