Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters with Interstellar Cold Clouds
Anna Nica, Merav Opher, Jesse A. Miller +1
Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit. This would expose Earth t…

The Effect of Magnetic Field Dissipation in the Inner Heliosheath: Reconciling Global Heliosphere Model and Voyager Data
Sergey D. Korolkov, Igor I. Baliukin, Merav Opher
Global ideal magnetohydrodynamic models of the heliosphere typically predict a greatly exaggerated magnetic field pile-up in the inner heliosheath (IHS), the region between the ter…

On the anisotropic velocity distribution of newborn pickup ions in the heliosheath
Senbei Du, Merav Opher, Marc Kornbleuth
The evolution of the velocity distribution of pickup ions is crucial for understanding the energetic neutral atom (ENA) fluxes observed by Interstellar Boundary Explorer (IBEX). Pi…
