Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...

The Relativistic Outflow Driven by the Large-scale Magnetic Field from an Accretion Disk
The Astrophysical JournalOutflows/jets are ubiquitous in a wide range of astrophysical objects, yet the mechanisms responsible for their generation remain elusive. One hypothesis is that they are magnetically driven.

Discovery of synchrotron emission from a YSO jet
EPJ Web of Conferences, 2013 Synchrotron emission at radio wavelengths is commonly found in relativistic jets from active galactic nuclei (AGNs) and microquasars and allows the study of the magnetic field in these kind of jets.

Stars Bisected by Relativistic Blades
The Astrophysical Journal Letters, 2023 We consider the dynamics of an equatorial explosion powered by a millisecond magnetar formed from the core collapse of a massive star. We study whether these outflows—generated by a priori magneto-centrifugally driven, relativistic magnetar winds—might ...

Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt
Space Weather, Volume 24, Issue 8, August 2026.Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract We investigated the spatial distributions and pitch‐angle distributions of 30–300 eV H+ and O+ ion fluxes using data obtained by the low‐energy particle experiments‐ion mass analyzer (LEPi) onboard the Arase satellite. A statistical analysis over 3.7 years reveals that the H+ ion flux is enhanced at L > 4 from the premidnight sector through ...

STABILITY OF RELATIVISTIC FORCE-FREE JETS [PDF]
The Astrophysical Journal, 2009 We consider a two-parameter family of cylindrical force-free equilibria, modeled to match numerical simulations of relativistic force-free jets. We study the linear stability of these equilibria, assuming a rigid impenetrable wall at the outer cylindrical radius R_j.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract The 1962 Starfish Prime high‐altitude 1.4‐megaton nuclear detonation injected large amounts of fission‐produced energetic electrons into the inner magnetosphere (L = 1.12), creating an intense artificial radiation belt that persisted for years. In this study, we revisit historical data from this unprecedented event to investigate the potential
