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…
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…
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…
Outflow Driven Cavities: Numerical Simulations of Intermediaries of Protostellar Turbulence
Andrew J. Cunningham, Adam Frank, Alice C. Quillen +1
We investigate the evolution of fossil cavities produced by extinct YSO jets and wide angle outflows. Fossil cavities are ellipsoidal or cylindrical shells of swept-up of ambient (…
Protostellar Jets and Turbulence in Molecular Clouds: The Role of Interactions
Andrew J. Cunningham, Adam Frank, Eric G. Blackman
We present a series of numerical studies of the interaction of colliding radiative, hydrodynamic young stellar outflows. We study the effect of the collision impact parameter on th…
Wide-Angle Wind Driven Bipolar Outflows: High Resolution Models with Application to Source I of the Becklin-Neugebauer / Kleinmann-Low OMC-I Region
Andrew Cunningham, Adam Frank, Lee Hartmann
We carry out high resolution simulations of the inner regions of a wide angle wind driven bipolar outflow using an Adaptive Mesh Refinement code. Our code follows H-He gas with mol…
