Hypersonic Buckshot: Astrophysical Jets as Heterogeneous Collimated Plasmoids
Kristopher Yirak, Adam Frank, Andrew J. Cunningham +1
Herbig-Haro (HH) jets are commonly thought of as homogeneous beams of plasma traveling at hypersonic velocities. Structure within jet beams is often attributed to periodic or ``pul…
Simulating Magnetohydrodynamical Flow with Constrained Transport and Adaptive Mesh Refinement; Algorithms & Tests of the AstroBEAR Code
Andrew J. Cunningham, Adam Frank, Peggy Varniere +2
A description is given of the algorithms implemented in the AstroBEAR adaptive mesh refinement code for ideal magnetohydrodynamics. The code provides several high resolution, shock…
PPN as Explosions: Bullets vs Jets and Nebular Shaping
Timothy J. Dennis, Andrew J. Cunningham, Adam Frank +3
Many proto-planetary nebulae (PPN) appear as narrow collimated structures sometimes showing multiple, roughly aligned lobes. In addition, many PPN flows have been shown to have sho…
The Interaction Between a Pulsed Astrophysical Jet and Small-Scale Heterogeneous Media
Kristopher Yirak, Adam Frank, Andrew Cunningham +1
We have performed 2D hydrodynamic simulations of a pulsed astrophysical jet propagating through a medium that is populated with spherical inhomogeneities, or "clumps," which are sm…
Evolution and Fragmentation of Wide-Angle Wind Driven Molecular Outflows
Andrew Cunningham, Adam Frank, Peggy Varnière +3
We present two dimensional cylindrically symmetric hydrodynamic simulations and synthetic emission maps of a stellar wind propagating into an infalling, rotating environment. The r…
Strings in the Eta Carinae Nebula: Hypersonic Radiative Cosmic Bullets
A. Y. Poludnenko, A. Frank, S. Mitran
We present the results of a numerical study focusing on the propagation of a hypersonic bullet subject to radiative cooling. Our goal is to explore the feasibility of such a model…
