Characterizing the Impact of Alfvén Wave Forcing in Interplanetary Space on the Distribution of Near-Earth Solar Wind Speeds

The Astrophysical Journal Letters
Broadly, solar wind source regions can be classified by their magnetic topology as intermittently and continuously open to the heliosphere. Early models of solar wind acceleration do not account for the fastest, nontransient solar wind speeds observed ...

Magnetic Connectivity in the Time-dependent Corona and Heliosphere

The Astrophysical Journal Letters
Magnetic flux fills the heliosphere, expands outward from the solar corona, and is fundamentally related to the structure and dynamics of the solar corona and solar wind.

Driving Dynamical Inner‐Heliosphere Models With In Situ Solar Wind Observations

Space Weather
Accurately reconstructing the solar wind throughout the inner heliosphere is essential for understanding solar–terrestrial interactions and improving space‐weather forecasts.

Simulating a Steady-state Heliosphere

The Astrophysical Journal Supplement Series
Ever since the discovery of the solar wind, it has been understood that our solar system resides within a bubble of solar wind plasma that originates from the Sun.

The Global Structure of the Heliosphere

The Astrophysical Journal
As the Sun moves through the local interstellar medium (LISM), it emits charged particles, creating the heliosphere occupied by the plasma of solar origin.

Ion-scale Turbulence and Energy Cascade Rate in the Solar Corona and Inner Heliosphere

The Astrophysical Journal Letters
Plasma turbulence cascading from MHD to kinetic scales in the heliospheric plasma is believed to play a key role in coronal heating and fast solar wind acceleration, but the properties of the turbulence remain poorly constrained by observations.

The Vigil Magnetometer for Operational Space Weather Services From the Sun‐Earth L5 Point

Space Weather
Severe space weather has the potential to cause significant socio‐economic impact and it is widely accepted that mitigating this risk requires more comprehensive observations of the Sun and heliosphere, enabling more accurate forecasting of significant ...

Interplay of Large-scale Drift and Turbulence in the Heliospheric Propagation of Solar Energetic Particles

The Astrophysical Journal
The gradient and curvature of the Parker spiral interplanetary magnetic field give rise to curvature and gradient guiding-center drifts on cosmic rays (CRs). The plasma turbulence present in interplanetary space is thought to suppress the drifts; however,
