Synchrotron Magnetic Fields from Rayleigh-Taylor Instability in Supernovae
Paul Duffell, Daniel Kasen
Synchrotron emission from a supernova necessitates a magnetic field, but it is unknown how strong the relevant magnetic fields are, and what mechanism generates them. In this study…

A Simple Analytical Model for Gaps in Protoplanetary Disks
Paul C. Duffell
An analytical model is presented for calculating the surface density as a function of radius in protoplanetary disks in which a planet has opened a gap. This model is also a…
