Resonant Chains of Exoplanets: Libration Centers for Three-body Angles
Jared Siegel, Daniel Fabrycky
Resonant planetary systems contain at least one planet pair with orbital periods librating at a near-integer ratio (2/1, 3/2, 4/3, etc.) and are a natural outcome of standard plane…

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…
