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…
Synergies between interstellar dust and heliospheric science with an Interstellar Probe
Veerle J. Sterken, Silvan Hunziker, Kostas Dialynas +40
We discuss the synergies between heliospheric and dust science, the open science questions, the technological endeavors and programmatic aspects that are important to maintain or d…
The Twist of the Draped Interstellar Magnetic Field Ahead of the Heliopause: A Magnetic Reconnection Driven Rotational Discontinuity
M. Opher, J. F. Drake, M. Swisdak +2
Based on the difference between the orientation of the interstellar and the solar magnetic fields, there was an expectation that the magnetic field direction would rotate…
Using ForeCAT Deflections and Rotations to Constrain the Early Evolution of CMEs
C. Kay, M. Opher, R. C. Colaninno +1
To accurately predict the space weather effects of coronal mass ejection (CME) impacts at Earth one must know if and when a CME will impact Earth, and the CME parameters upon impac…
Cross and magnetic helicity in the outer heliosphere from Voyager 2 observations
M. Iovieno, L. Gallana, F. Fraternale +3
Plasma velocity and magnetic field measurements from the Voyager 2 mission are used to study solar wind turbulence in the slow solar wind at two different heliocentric distances, 5…
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…
Forecasting a Coronal Mass Ejection's Altered Trajectory: ForeCAT
Christina Kay, Merav Opher, Rebekah M. Evans
To predict whether a coronal mass ejection (CME) will impact Earth, the effects of the background on the CME's trajectory must be taken into account. We develop a model, ForeCAT (F…
