Terrestrial Impact from the Passage of the Solar System through a Cold Cloud a Few Million Years Ago
Merav Opher, Abraham Loeb
It is expected that as the Sun travels through the interstellar medium (ISM), there will be different filtration of Galactic Cosmic Rays (GCR) that affect Earth. The effect of GCR…
On the Rotation of the Magnetic Field Across the Heliopause
Merav Opher, James F. Drake
There was an expectation that the magnetic field direction would rotate dramatically across the heliopause (HP). This rotation was used as one of the criteria to determine if Voyag…
The Energy of a Plasma in the Classical Limit
Merav Opher, Reuven Opher
When λ_{T} << d_{T}, where λ_{T} is the de Broglie wavelength and d_{T}, the distance of closest approach of thermal electrons, a classical analysis of the energy of a plasma can…
Two-Dimensional Kelvin-Helmholtz Instability with Anisotropic Pressure
Shishir Biswas, Masaru Nakanotani, Dinshaw S. Balsara +2
The Kelvin-Helmholtz (KH) instability occurs in multiple heliospheric (solar-wind stream interfaces, planetary magnetospheres, cometary tails, heliopause flanks) and interstellar (…
Voyager 2 solar plasma and magnetic field spectral analysis for intermediate data sparsity
Luca Gallana, Federico Fraternale, Michele Iovieno +5
The Voyager probes are the furthest, still active, spacecraft ever launched from Earth. During their 38-year trip, they have collected data regarding solar wind properties (such as…
Trajectories of Coronal Mass Ejection from Solar-type Stars
Fabian Menezes, Adriana Valio, Yuri Netto +3
The Sun and other solar-type stars have magnetic fields that permeate their interior and surface, extends through the interplanetary medium, and is the main driver of stellar activ…
