Spatial Distribution of Mg-Rich Ejecta in LMC Supernova Remnant N49B
Sangwook Park, Jayant Bhalerao
The supernova remnant (SNR) N49B in the Large Magellanic Cloud is a peculiar example of a core-collapse SNR to show the shocked metal-rich ejecta enriched only in Mg without eviden…
The Origin of the Iron-Rich Knot in Tycho's Supernova Remnant
Hiroya Yamaguchi, John P. Hughes, Carles Badenes +5
X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta, offering unique insight into the nucleosynthesis in supernova explosio…
Chandra Observes the End of an Era SN 1987A
Kari A. Frank, Svetozar A. Zhekov, Sangwook Park +3
Updated imaging and photometric results from Chandra observations of SN 1987A, covering the last 16 years, are presented. We find that the 0.5-2 keV light curve has remained consta…
A Chandra Study of the Interstellar Metallicity in the Large Magellanic Cloud Using Supernova Remnants
Andrew Schenck, Sangwook Park, Seth Post
We report on the results from our measurements of the interstellar medium (ISM) abundances for the elements O, Ne, Mg, Si, and Fe in the Large Magellanic Cloud (LMC). We used the a…
Infrared Continuum and Line Evolution of the Equatorial Ring around SN 1987A
Richard G. Arendt, Eli Dwek, Patrice Bouchet +5
Spitzer observations of SN 1987A have now spanned more than a decade. Since day ~4,000, mid-infrared (mid-IR) emission has been dominated by that from shock-heated dust in the equa…
