Latest Evolution of the X-Ray Remnant of SN 1987A: Beyond the Inner Ring

Aravind P. Ravi, Sangwook Park, Svetozar A. Zhekov +5

Based on our Chandra imaging-spectroscopic observations, we present the latest evolution of the X-ray remnant of SN 1987A. Recent changes in the electron temperatures and volume em…

Spectral Evolution of the X-Ray Remnant of SN 1987A: A High-Resolution HETG Study

Aravind P. Ravi, Sangwook Park, Svetozar A. Zhekov +4

Based on observations with the X-ray Observatory, we present the latest spectral evolution of the X-ray remnant of SN 1987A (SNR 1987A). We present a high-resolution spec…

Can the Fe K-alpha Line Reliably Predict Supernova Remnant Progenitors?

Jared Siegel, Vikram V. Dwarkadas, Kari A. Frank +1

The centroid energy of the Fe K line has been used to identify the progenitors of supernova remnants (SNRs). These investigations generally considered the energy of the centroid…

Analysis of XMM-Newton Observations of Supernova Remnant W49B and Clues to the Progenitor

Jared Siegel, Vikram V. Dwarkadas, Kari A. Frank +1

W49B is a supernova remnant (SNR) discovered over 60 years ago in early radio surveys. It has since been observed over the entire wavelength range, with the X-ray morphology resemb…

SPI Analysis and Abundance Calculations of DEM L71, and Comparison to SN explosion Models

Jared Siegel, Vikram V. Dwarkadas, Kari Frank +2

We analyze the X-Ray emission from the supernova remnant DEM L71 using the Smoothed Particle Inference (SPI) technique. The high Fe abundance found appears to confirm the Type Ia o…

Smoothed Particle Inference Analysis of SNR DEM L71

Kari A. Frank, Vikram Dwarkadas, Aldo Panfichi +2

Supernova remnants (SNRs) are complex, three-dimensional objects; properly accounting for this complexity when modeling the resulting X-ray emission presents quite a challenge and…
