BepiColombo mission confirms stagnation region of Venus and reveals its large extent

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-10 (2022)

BepiColombo mission had two Venus flybys on its way to Mercury. Here, the authors show that during its second flyby of Venus BepiColombo has crossed the stagnation region, which was predicted by the models.

A Rapid Sequence of Solar Energetic Particle Events Associated with a Series of Extreme-ultraviolet Jets: Solar Orbiter, STEREO-A, and Near-Earth Spacecraft Observations

Publikováno v: The Astrophysical Journal, Vol 975, Iss 1, p 84 (2024)

A series of solar energetic electron (SEE) events was observed from 2022 November 9 to November 15 by Solar Orbiter, STEREO-A, and near-Earth spacecraft. At least 32 SEE intensity enhancements at energies >10 keV were clearly distinguishable in Solar

Magnetic Field Spectral Evolution in the Inner Heliosphere

Publikováno v: The Astrophysical Journal Letters, Vol 943, Iss 1, p L8 (2023)

Parker Solar Probe and Solar Orbiter data are used to investigate the radial evolution of magnetic turbulence between 0.06 ≲ R ≲ 1 au. The spectrum is studied as a function of scale, normalized to the ion inertial scale d _i . In the vicinity of

On the Evolution of the Anisotropic Scaling of Magnetohydrodynamic Turbulence in the Inner Heliosphere

Publikováno v: The Astrophysical Journal, Vol 951, Iss 2, p 141 (2023)

We analyze a merged Parker Solar Probe (PSP) and Solar Orbiter (SO) data set covering heliocentric distances 13 R _⊙ ≲ R ≲ 220 R _⊙ to investigate the radial evolution of power and spectral index anisotropy in the wavevector space of solar wi

Observational Evidence of S-web Source of the Slow Solar Wind

Publikováno v: The Astrophysical Journal, Vol 950, Iss 1, p 65 (2023)

From 2022 March 18 to 21, NOAA Active Region (AR) 12967 was tracked simultaneously by Solar Orbiter at 0.35 au and Hinode/EIS at Earth. During this period, strong blueshifted plasma upflows were observed along a thin, dark corridor of open magnetic f

Publikováno v: The Astrophysical Journal, Vol 945, Iss 1, p 28 (2023)

We present EUV solar observations showing evidence for omnipresent jetting activity driven by small-scale magnetic reconnection at the base of the solar corona. We argue that the physical mechanism that heats and drives the solar wind at its source i

Magnetosheath dynamic pressure enhancements: occurrence and typical properties

Autor: M. O. Archer, T. S. Horbury

Publikováno v: Annales Geophysicae, Vol 31, Pp 319-331 (2013)

The first comprehensive statistical study of large-amplitude (> 100%) transient enhancements of the magnetosheath dynamic pressure reveals events of up to ~ 15 times the ambient dynamic pressure with durations up to 3 min and an average duration o

The expected imprint of flux rope geometry on suprathermal electrons in magnetic clouds

Autor: M. J. Owens, N. U. Crooker, T. S. Horbury

Publikováno v: Annales Geophysicae, Vol 27, Pp 4057-4067 (2009)

Magnetic clouds are a subset of interplanetary coronal mass ejections characterized by a smooth rotation in the magnetic field direction, which is interpreted as a signature of a magnetic flux rope. Suprathermal electron observations indicate that
