Effects of Dispersion of the Dust Velocity in the LISM on the Interstellar Dust Distribution inside the Heliosphere [PDF]
Astronomy letters, 2021 Interstellar dust (ISD) penetrates into the heliosphere due to the relative motion of the Sun and the local interstellar medium (LISM). Inside the heliosphere and at the boundaries, where solar wind interacts with the LISM, distribution of ISD is ...

MANIFESTATIONS OF TWO BRANCHES OF SOLAR ACTIVITY IN THE HELIOSPHERE AND GCR INTENSITY
Solar-Terrestrial Physics, 2019 This paper provides insight into heliospheric processes and galactic cosmic ray (GCR) modulation occurring due to the presence of two branches of solar activity in this solar layer.

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.

Sun–Heliosphere Observation-based Ionization Rates Model [PDF]
Astrophysical Journal, 2020 The solar wind (SW) and the extreme ultraviolet (EUV) radiation modulate fluxes of interstellar and heliospheric particles inside the heliosphere both in time and in space. Understanding this modulation is necessary to correctly interpret measurements of

Enhanced proton parallel temperature inside patches of switchbacks in the inner heliosphere [PDF]
Astronomy & Astrophysics, 2020 Context. Switchbacks are discrete angular deflections in the solar wind magnetic field that have been observed throughout the heliosphere. Recent observations by Parker Solar Probe (PSP) have revealed the presence of patches of switchbacks on the scale ...

Redefining flux ropes in heliophysics
Frontiers in Astronomy and Space Sciences, 2023 Magnetic flux ropes manifest as twisted bundles of magnetic field lines. They carry significant amounts of solar mass in the heliosphere. This paper underlines the need to advance our understanding of the fundamental physics of heliospheric flux ropes ...

Plasma Dynamics in Low-Electron-Beta Environments
Frontiers in Astronomy and Space Sciences, 2021 Recent in situ measurements by the MMS and Parker Solar Probe missions bring interest to small-scale plasma dynamics (waves, turbulence, magnetic reconnection) in regions where the electron thermal energy is smaller than the magnetic one.

A Model for the Sources of the Slow Solar Wind [PDF]
, 2011 Models for the origin of the slow solar wind must account for two seemingly contradictory observations: The slow wind has the composition of the closed field corona, implying that it originates from the continuous opening and closing of flux at the ...

Ion-scale Electromagnetic Waves in the Inner Heliosphere [PDF]
Astrophysical Journal Supplement Series, 2019 Understanding the physical processes in the solar wind and corona that actively contribute to heating, acceleration, and dissipation is a primary objective of NASA’s Parker Solar Probe (PSP) mission.
