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 ...

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

Geophysical Research Letters
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 interstellar galactic cosmic rays and energetic particles of heliospheric origin.

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,

THE SUN AND THE HELIOSPHERE IN FEBRUARY-MARCH, 1986

THE SUN AND THE HELIOSPHERE IN FEBRUARY-MARCH, 1986
Conditions of the sun and the heliosphere are studied in relation to the intense disturbances of the earth's and cometary magnetospheres in February and March, 1986. In this sunspot minimum phase, the sun had essentially the southward axial dipole which was to produce a weak northward IMF. However, one bipolar magnetic region in the northern hemisphere

Astrospheres and Solar-like Stellar Winds

Living Reviews in Solar Physics, 2004
Stellar analogs for the solar wind have proven to be frustratingly difficult to detect directly. However, these stellar winds can be studied indirectly by observing the interaction regions carved out by the collisions between these winds and the ...
