About Cosmic Ray Modulation in the Heliosphere
Universe, 2022 Cosmic ray fluxes in the heliosphere are modulated by solar wind with an embedded solar interplanetary magnetic field. The solar activity changes with a period of ~11 year, and this is the main reason for the observed 11-year variations of cosmic ray ...

The Sun as a driver of the inner heliosphere: Modern investigations of fundamental plasma processes [PDF]
Nature CommunicationsThe inner heliosphere serves as a natural laboratory to study fundamental plasma physics. A robust understanding of kinetic processes will fill gaps in our global understanding of the Sun and heliosphere, with applicability to laboratory and ...

Solar wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics (SHIELD) DRIVE Science Center
Frontiers in Astronomy and Space Sciences, 2023 Most stars generate winds and move through the interstellar medium that surrounds them. This movement creates a cocoon formed by the deflection of these winds that envelops and protects the stars. We call these “cocoons” astrospheres. The Sun has its own

Global insight into a complex-structured heliosphere based on the local multi-point analysis
Frontiers in Astronomy and Space Sciences, 2023 From 29 January to 7 February 2022, the heliosphere was structured with large-scale interacting substructures that appeared with significant dissimilarities at distant observations separated longitudinally by ∼34°.

Manifestation of solar wind corotating interaction regions in GCR intensity variations
Solar-Terrestrial Physics, 2023 The regions of interaction between solar wind streams of different speed, known as corotating interaction regions, form an almost constantly existing structure of the inner heliosphere.

Numerical modeling of solar wind and coronal mass ejection in the inner heliosphere: A review
Frontiers in Astronomy and Space Sciences, 2023 The predictions of plasma parameters in the interplanetary medium are the core of space weather forecasts, and the magnetohydrodynamics (MHD) numerical simulation is an important tool in the prediction of plasma parameters.

Eruption and Interplanetary Evolution of a Stealthy Streamer-Blowout CME Observed by PSP at ∼0.5 AU
Frontiers in Astronomy and Space Sciences, 2022 Streamer-blowout coronal mass ejections (SBO-CMEs) are the dominant CME population during solar minimum. Although they are typically slow and lack clear low-coronal signatures, they can cause geomagnetic storms.
