Abstract The Solar Wind Electrons Alphas and Protons (SWEAP) Investigation on Solar
Probe Plus is a four sensor instrument suite that provides complete measurements of the …

The solar wind is a magnetized plasma and as such exhibits collective plasma behavior
associated with its characteristic spatial and temporal scales. The characteristic length …

We review our state of knowledge of coronal element abundance anomalies in the Sun and
stars. We concentrate on the first ionization potential (FIP) effect observed in the solar …

In situ measurements of the solar wind have been available for almost 60 years, and in that
time plasma physics simulation capabilities have commenced and ground‐based solar …

The Wind spacecraft, launched on November 1, 1994, is a critical element in NASA's
Heliophysics System Observatory (HSO)—a fleet of spacecraft created to understand the …

While it is certain that the fast solar wind originates from coronal holes, where and how the
slow solar wind (SSW) is formed remains an outstanding question in solar physics even in …

We seek to understand the composition and variability of fast solar wind (FSW) and slow
Alfvénic solar wind emerging from coronal holes (CHs). We leverage an opportune …

In fast wind or when the local Coulomb collision frequency is low, observations show that
solar wind minor ions and ion subpopulations flow with different bulk velocities …

Comparative studies of fast and slow solar wind streams performed over the past decades
have illustrated several differences between the plasma regimes for these different flows …
