The Electron Structure of the Solar Wind

Frontiers in Astronomy and Space Sciences, 2021
Time-series measurements of the number density ncore and temperature Tcore of the core-electron population of the solar wind are examined at 1 AU and at 0.13 AU using measurements from the WIND and Parker Solar Probe spacecraft, respectively.

The Heliospheric Meteorology Mission: A Mission to DRIVE our Understanding of Heliospheric Variability

Frontiers in Astronomy and Space Sciences, 2018
To make transformational scientific progress with the space weather enterprise the Sun, Earth, and heliosphere must be studied as a coupled system, comprehensively. Rapid advances were made in the study, and forecasting, of terrestrial meteorology half a

Solar wind and kinetic heliophysics [PDF]

Annales Geophysicae, 2018
This paper reviews recent aspects of solar wind physics and elucidates the role Alfvén waves play in solar wind acceleration and turbulence, which prevail in the low corona and inner heliosphere.

Dust in the Local Interstellar Wind [PDF]

, 1999
The gas-to-dust mass ratios found for interstellar dust within the Solar System, versus values determined astronomically for the cloud around the Solar System, suggest that large and small interstellar grains have separate histories, and that large ...

Exclusion of Tiny Interstellar Dust Grains from the Heliosphere [PDF]

, 2009
The distribution of interstellar dust grains (ISDG) observed in the Solar System depends on the nature of the interstellar medium-solar wind interaction.

The Sun and heliosphere explorer – the Interhelioprobe mission

Geomagnetism and Aeronomy, 2016
The Interhelioprobe mission aims to investigate the inner heliosphere and the Sun from close distances (up to 0.3 AU) and from out of the ecliptic plane (up to 30°). In this paper we present the relevance of the mission and its main scientific objectives, describe the scientific payload, ballistic scenario and orbits of the spacecraft. Possibilities of

Inverse Compton scattering on solar photons, heliospheric modulation, and neutrino astrophysics [PDF]

, 2006
We study the inverse Compton scattering of solar photons by Galactic cosmic-ray electrons. We show that the gamma-ray emission from this process is substantial with the maximum flux in the direction of the Sun; the angular distribution of the emission is

Galactic Abundances: Report of Working Group 3 [PDF]

, 2001
We summarize the various methods and their limitations and strengths to derive galactic abundances from in-situ and remote-sensing measurements, both from ground-based observations and from instruments in space. Because galactic abundances evolve in time
