Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters with Interstellar Cold Clouds
Anna Nica, Merav Opher, Jesse A. Miller +2
Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interst…
Earth's Mesosphere During Possible Encounters With Massive Interstellar Clouds 2 and 7 Million Years Ago
Jesse A. Miller, Merav Opher, Maria Hatzaki +2
Our solar system's path has recently been shown to potentially intersect dense interstellar clouds 2 and 7 million years ago: the Local Lynx of Cold Cloud and the edge of the Local…
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…
The Vector Direction of the Interstellar Magnetic Field Outside the Heliosphere
M. Swisdak, M. Opher, J. F. Drake +1
We propose that magnetic reconnection at the heliopause only occurs where the interstellar magnetic field points nearly anti-parallel to the heliospheric field. By using large-scal…
A model of acceleration of Anomalous Cosmic Rays by Reconnection in the Heliosheath
A. Lazarian, M. Opher
We discuss a model of cosmic ray acceleration that accounts for the observations of anomalous cosmic rays by Voyager 1 and 2. The model appeals to fast magnetic reconnection rather…
