Using sunRunner3D to interpret the global structure of the heliosphere from in situ measurements

open access: yesJournal of Space Weather and Space Climate
Understanding the large-scale three-dimensional structure of the inner heliosphere, while important in its own right, is crucial for space weather applications, such as forecasting the time of arrival and propagation of coronal mass ejections (CMEs ...

Elemental abundances in corotating events [PDF]

open access: yes, 1985
Large, persistent solar-wind streams in 1973 and 1974 produced corotating interaction regions which accelerated particles to energies of a few MeV/nucleon.

Corotating Interaction Regions and clumping

open access: yes, 2008
We present hydrodynamical models for Corotating Interaction Regions, which were used by Lobel (2007) to model the Discrete Absorption Components in HD 64760.

Quiet-time Spectra of Suprathermal Heavy Ions near 1 au in Solar Cycles 23 and 24

open access: yesThe Astrophysical Journal Letters
We report on the annual variation of quiet-time suprathermal heavy ion spectral indices for C through Fe in the energy range 0.3–1.28 MeV nuc ^−1 during Solar Cycle 23's rising phase through Solar Cycle 24's declining phase.

STRUCTURE OF A MAGNETIC DECREASE OBSERVED IN A COROTATING INTERACTION REGION

open access: yesJournal of The Korean Astronomical Society, 2016
Magnetic decreases are often observed in various regions of interplanetary space. Many studies are devoted to reveal the physical nature and generation mechanism of the magnetic decreases, but still we do not fully understand magnetic decreases. In this study, we investigate the structure of a magnetic decrease observed in a corotating interaction ...

CLASSIFICATION ALGORITHM FOR MHD WAVELET-SKELETON SPECTRAL IMAGES OF GEOEFFECTIVE PLASMA FLOWS IN THE SOLAR WIND

open access: yesВестник Мининского университета, 2017
The paper presents a new method for the identification of plasma flows in the solar wind by self-learning classification neural network using their spectral features in the range of magnetic hydrodynamics.

Interaction between a Coronal Mass Ejection and Comet 67P/Churyumov–Gerasimenko

open access: yesThe Astrophysical Journal
The interaction between a coronal mass ejection (CME) and a comet has been observed several times by in situ observations from the Rosetta Plasma Consortium, which is designed to investigate the cometary magnetosphere of comet 67P/Churyumov–Gerasimenko ...

Modeling energetic proton transport in a corotating interaction region

open access: yesAstronomy & Astrophysics
Aims. An energetic particle event related to a corotating interaction region (CIR) structure was observed by the Solar-Terrestrial Relations Observatory-A (STEREO-A) from 21 to 24 August 2016. Based on an analysis of measurement data, we suggest that instead of being accelerated by distant shocks, a local mechanism similar to diffusive shock ...

Prediction for Arrival Time and Parameters of Corotation Interaction Regions using Earth–Mars Correlated Events from Tianwen-1, MAVEN, and Wind Observations

open access: yesThe Astrophysical Journal
Using the Stream Interaction Regions list from the Tianwen-1/Mars Orbiter Magnetometer (MOMAG) data between 2021 November and 2021 December and from Wind observations, we present an accurate prediction for the arrival time and in situ parameters of ...

Variable Linear Polarization across Optical Emission Lines of the Wolf–Rayet Star EZ Canis Majoris and Its Relation to Corotating Interaction Regions

open access: yesThe Astrophysical Journal
Structure can be found on all scales in the winds of hot, luminous stars, including Wolf–Rayet (W-R) stars. Large-scale, spiral-shaped corotating interaction regions (CIRs) are thought to be present, causing quasi-periodic variability.
