Dependence of the MHD shock thickness on the finite electrical conductivity
A. Kandus, R. Opher
The results of MHD plane shock waves with infinite electrical conductivity are generalized for a plasma with a finite conductivity. We derive the adiabatic curves that describe the…
Alfven Waves in Disks, Outflows and Jets
Reuven Opher
Observations of young stellar objects, such as classical T Tauri stars (CTTSs), show evidence of accretion disks (ADs), outflows and jets. It is shown that Alfven waves (AWs) are i…
Numerical Simulations of Astrophysical Jets from Keplerian Disks with Periodic Ejection
B. F. Vitorino, V. Jatenco-Pereira, R. Opher
We present 2.5-dimensional time-dependent simulations of nonrelativistic and nonradiative outflows from sinusoidally perturbed Keplerian accretion disks. A sinusoidal perturbation…
Ten Major Challenges in Cosmology
Reuven Opher
What are the important unanswered questions in cosmology? The choice as to which are the most important is somewhat personal. In the view of the author, the ten topics chosen here…
