Be star discs: powered by a non-zero central torque
Chris Nixon, Jim Pringle
Be stars are rapidly rotating B stars with Balmer emission lines that indicate the presence of a Keplerian, rotationally supported, circumstellar gas disc. Current disc models, ref…
Nonthermal filaments from the tidal destruction of clouds in the Galactic center
Eric R. Coughlin, C. J. Nixon, Adam Ginsburg
Synchrotron-emitting, nonthermal filaments (NTFs) have been observed near the Galactic center for nearly four decades, yet their physical origin remains unclear. Here we investigat…
The persistence of pancakes and the revival of self-gravity in tidal disruption events
Eric R. Coughlin, C. J. Nixon, Patrick R. Miles
The destruction of a star by the tides of a supermassive black hole (SMBH) powers a bright accretion flare, and the theoretical modeling of such tidal disruption events (TDEs) can…
Accretion discs with non-zero central torque
C. J. Nixon, J. E. Pringle
We present analytical and numerical solutions for accretion discs subject to a non-zero central torque. We express this in terms of a single parameter, , which is the ratio of o…
Instability of non-Keplerian warped discs
Suzan Dogan, Chris Nixon
Many accretion discs are thought to be warped. Recent hydrodynamical simulations show that (i) discs can break into distinct planes when the amplitude of an imposed warp is suffici…
The Gravitational Instability of Adiabatic Filaments
Eric R. Coughlin, C. J. Nixon
Filamentary structures, or long and narrow streams of material, arise in many areas of astronomy. Here we investigate the stability of such filaments by performing an eigenmode ana…
