Impact Plasma Amplification of the Ancient Mercury Magnetic Field

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Protoplanet magnetosphere interactions [PDF]

Astronomy & Astrophysics, 2006
In this paper, we study a simple model of an orbiting protoplanet in a central magnetospheric cavity, the entry into such a cavity having been proposed as a mechanism for halting inward orbital migration. We have calculated the gravitational interaction of the protoplanet with the magnetosphere using a local model and determined the rate of evolution ...

Control of the Jovian Magnetopause by Iogenic Plasma: Initial Results From Global MHD Simulations

Geophysical Research Letters
The size and variability of Jupiter's magnetosphere are not only determined by upstream conditions but also substantially influenced by internal processes within Jupiter's magnetosphere, specifically the dynamics of the rotation magnetodisc.

Storm‐Time Dst Forecast: An Innovative Approach

Space Weather, Volume 24, Issue 5, May 2026.
Abstract One of the most persistent challenges in the space weather field is predicting the storm‐time response of the geospace without knowing the predicted drivers in the solar wind. Here, a new pattern recognition algorithm is developed to predict storm‐time Dst index from 1 hr to ∼4.5 days into the future. Storm‐time Dst patterns (or reference Dst)

Accretion, Outflows, and Winds of Magnetized Stars

, 2016
Many types of stars have strong magnetic fields that can dynamically influence the flow of circumstellar matter. In stars with accretion disks, the stellar magnetic field can truncate the inner disk and determine the paths that matter can take to flow ...

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

Solar Wind‐Magnetosphere‐Ionosphere Coupling During the October 2024 Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Two geomagnetic storms occurred in October 2024 (Oct 6‐9 and 10–12), driven by the impact of a series of interplanetary coronal mass ejections on the magnetosphere. The first was a moderate storm, with peak Sym‐H near −150 nT, whereas the second was intense, Sym‐H reaching −340 nT.

Explicit IMF By Dependence in Geomagnetic Activity: Modulation of Precipitating Electrons

Geophysical Research Letters, 2020
The most important driver of geomagnetic activity is the north–south ( Bz) component of the interplanetary magnetic field (IMF), which dominates the solar wind‐magnetosphere coupling and all solar wind coupling functions.

A correlative investigation of the propagation of ULF wave power through the dayside magnetosphere [PDF]

Three different ULF wave phenomena (azimuthally polarized Pc 3 pulsations, radially polarized Pc 4 pulsations, and solitary Pc 5 pulsations related to solar wind pressure pulses) were studied. The main problems covered are: (1) how do magnetospheric Pc 3-

Activated Magnetospheres of Magnetars

, 2010
Like the solar corona, the external magnetic field of magnetars is twisted by surface motions of the star. The twist energy is dissipated over time. We discuss the theory of this activity and its observational status.
