Prediction for IMAP: Revealing the Role of the Solar Magnetic Field in the Heliotail
M. Kornbleuth, M. Opher
The classic paradigm of the heliosphere considered the solar magnetic field as having a passive role in the heliosheath, yet Opher et al. (2015) and Drake et al. (2015) suggested t…
Dynamics of the Upwind Heliosphere Due to Data-Driven, Solar Wind and Magnetic Field Variations and Implications for Wave Propagation into the Very Local Interstellar Medium
Chika Onubogu, M. Opher, E. Powell +4
We introduce an updated, time-dependent treatment to the split-tail ("croissant-like") heliosphere model with data-driven solar wind conditions at 1 au, to study the evolution of t…
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 (…
Increased and Varied Radiation during the Sun's Encounters with Cold Clouds in the last 10 million years
Merav Opher, Joe Giacalone, Abraham Loeb +7
Recent research raises the possibility that 3 and 7 million years ago, the Sun encountered massive clouds that shrank the heliosphere--the solar cocoon protecting our solar system-…
The Solar System's passage through the Radcliffe wave during the middle Miocene
E. Maconi, J. Alves, C. Swiggum +14
Context. As the Solar System orbits the Milky Way, it encounters various Galactic environments, including dense regions of the interstellar medium (ISM). These encounters can compr…
