When Shock Waves Collide
P. Hartigan, J. Foster, A. Frank +10
Supersonic outflows from objects as varied as stellar jets, massive stars and novae often exhibit multiple shock waves that overlap one another. When the intersection angle between…
The Evolution of Hetergeneous "Clumpy Jets": A Parameter Study
Kristopher Yirak, Ed Schroeder, Adam Frank +1
We investigate the role discrete clumps embedded in an astrophysical jet play on the jet's morphology and line emission characteristics. By varying clumps' size, density, position,…
Self-Convergence of Radiatively Cooling Clumps
Kristopher Yirak, Adam Frank, Andrew J. Cunningham
Numeric convergence studies demonstrate that the evolution of an adiabatic clump is well-captured by roughly 100 cells per clump radius. The presence of radiative cooling, however,…
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…
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…
SDSS J210014.12+004446.0: A New Dwarf Nova with Quiescent Superhumps?
Jonica Tramposch, Lee Homer, Paula Szkody +5
We report follow-up observations of the Sloan Digital Sky Survey Cataclysmic Variable SDSS J210014.12+004446.0 (hereafter SDSS J2100). We obtained photometry and spectroscopy in bo…
