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…
Protostellar Outflow Evolution in Turbulent Environments
Andrew J. Cunningham, Adam Frank, Jonathan Carroll +2
The link between turbulence in star formatting environments and protostellar jets remains controversial. To explore issues of turbulence and fossil cavities driven by young stellar…
Outflow Driven Turbulence in Molecular Clouds
Jonathan J. Carroll, Adam Frank, Eric G. Blackman +2
In this paper we explore the relationship between protostellar outflows and turbulence in molecular clouds. Using 3-D numerical simulations we focus on the hydrodynamics of multipl…
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…
