X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta,
offering unique insight into the nucleosynthesis in supernova explosions. Here we present detailed imaging and
spectroscopic studies of the “Fe knot” located along the eastern rim of the Type Ia SNR Tycho (SN 1572) using
Suzaku and Chandra long-exposure data. Surprisingly, the Suzaku spectrum of this knot shows no emission from
Cr, Mn, or Ni, which is unusual for the Fe-rich regions...[Show more]
