Surface Alfven Wave Damping in a 3D Simulation of the Solar Wind
R. M. Evans, M. Opher, V. Jatenco-Pereira +1
Here we investigate the contribution of surface Alfven wave damping to the heating of the solar wind in minima conditions. These waves are present in regions of strong inhomogeneit…
Turbulence in the solar wind: spectra from Voyager 2 data at 5 AU
F. Fraternale, L. Gallana, M. Iovieno +3
Fluctuations in the flow velocity and magnetic fields are ubiquitous in the Solar System. These fluctuations are turbulent, in the sense that they are disordered and span a broad r…
Propagation into the heliosheath of a large-scale solar wind disturbance bounded by a pair of shocks
E. Provornikova, M. Opher, V. Izmodenov +1
After the termination shock (TS) crossing, the Voyager 2 spacecraft has been observing strong variations of the magnetic field and solar wind parameters in the heliosheath. Anomalo…
Is the magnetic field in the heliosheath laminar or a turbulent bath of bubbles?
M. Opher, J. F. Drake, M. Swisdak +4
All the current global models of the heliosphere are based on the assumption that the magnetic field in the heliosheath, in the region close to the heliopause is laminar. We argue…
Signature of a heliotail organized by the solar magnetic field and the role of non-ideal processes in modeled IBEX ENA maps: a comparison of the BU and Moscow MHD models
M. Kornbleuth, M. Opher, I. Baliukin +9
Energetic neutral atom (ENA) models typically require post-processing routines to convert the distributions of plasma and H atoms into ENA maps. Here we investigate how two differe…
Magnetic Effects Change Our View of the Heliosheath
M. Opher, P. C. Liewer, M. Velli +5
There is currently a controversy as to whether Voyager 1 has already crossed the Termination Shock, the first boundary of the Heliosphere. The region between the Termination Shock…
