The Effectiveness of the Kozai Mechanism in the Galactic Centre
P. Chang
I examine the effectiveness of Kozai oscillations in the centres of galaxies and in particular the Galactic centre using standard techniques from celestial mechanics. In particular…
Migration of Star Clusters and Nuclear Rings
Glenn van de Ven, Philip Chang
Star clusters that form in nuclear rings appear to be at slightly larger radii than the gas. We argue that the star clusters move out from the gas in which they are formed because…
Long Term Evolution of Magnetic Turbulence in Relativistic Collisionless Shocks
Philip Chang, Anatoly Spitkovsky, Jonathan Arons
We study the long term evolution of magnetic fields generated by an initially unmagnetized collisionless relativistic shock. Our 2D particle-in-cell numerical simulations…
Convection during the Late Stages of Simmering in Type Ia Supernovae
Anthony L. Piro, Philip Chang
Following unstable ignition of carbon, but prior to explosion, a white dwarf (WD) in a Type Ia supernova (SN Ia) undergoes a simmering phase. During this time, a central convective…
Gas Shepherding by an Infalling Satellite
P. Chang
I calculate the action of a satellite, infalling through dynamical friction, on a coplanar gaseous disk of finite radial extent. The disk tides, raised by the infalling satellite,…
Long Term Evolution of Magnetic Turbulence in Relativistic Collisionless Shocks: Electron-Positron Plasmas
P. Chang, A. Spitkovsky, J. Arons
We study the long term evolution of magnetic fields generated by a collisionless relativistic shock which is initially unmagnetized. Our 2D particle-in-cell numerical simu…
