Explosions in Roche-Lobe Distorted Stars: Relativistic Bullets in Binaries
Marcus DuPont, Andrew MacFadyen, Selma de Mink
State-of-the-art surveys reveal that most massive stars in the universe evolve in close binaries. Massive stars in such systems are expected to develop aspherical envelopes due to…

Stars Bisected by Relativistic Blades
Marcus DuPont, Andrew MacFadyen
We consider the dynamics of an equatorial explosion powered by a millisecond magnetar formed from the core collapse of a massive star. We study whether these outflows -- generated…

On The Theory of Ring Afterglows
Marcus DuPont, Andrew MacFadyen, Re'em Sari
Synchrotron and inverse Compton emission successfully explain the observed spectra of gamma-ray burst (GRB) afterglows. It is thought that most GRBs are products of extremely relat…
