In Situ Observations of Interplanetary Dust Variability in the Inner Heliosphere

Astrophysical Journal, 2020
This work examines the variation of interplanetary dust count rates and directionality during the first three solar encounters made by the Parker Solar Probe spacecraft, covering distances between 0.65 au (∼140 solar radii, RS) and 0.16 au (∼35 RS). Dust

Collisional thermalization of minor ions in the solar wind

Frontiers in Astronomy and Space Sciences
IntroductionAs the solar wind transits through the heliosphere, Coulomb collisions among constituent particles drives it toward local thermodynamic equilibrium. Prior studies of ion collisions in the solar wind have focused on the two most abundant solar

Slowing of the Solar Wind in the Outer Heliosphere

Astrophysical Journal, 2019
This study provides a deeper understanding of how the solar wind evolves with increasing distance from the Sun as it encounters an increasing amount of interstellar material.

Earth's Mesosphere During Possible Encounters With Massive Interstellar Clouds 2 and 7 Million Years Ago

Geophysical Research Letters
Our solar system's path has recently been shown to potentially intersect dense interstellar clouds 2 and 7 million years ago: the Local Lynx of Cold Cloud and the edge of the Local Bubble.

Long-term solar activity and its implications to the heliosphere, geomagnetic activity, and the Earth’s climate

Journal of Space Weather and Space Climate, 2013
The Sun’s long-term magnetic variability is the primary driver of space climate. This variability is manifested not only in the long-observed and dramatic change of magnetic fields on the solar surface, but also in the changing solar radiative output ...

Modulation of Galactic Cosmic Rays from Helium to Nickel in the Inner Heliosphere

Astrophysical Journal, 2019
Galactic cosmic-ray (GCR) helium and heavier ions are important sources of space radiation, and their elemental spectra and composition can help us better understand the transport in both the galaxy and the heliosphere.
