Outer‐Plasmasphere Plasma Hole Scenarios Promoting Hot Zone and Sub‐Auroral Polarization Streams (SAPS) E Field Development

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract In this study we investigate the nightside outer‐plasmasphere plasma hole developed near the magnetic equatorial plane in two different scenarios. We demonstrate the plasmasheet earthward termination with scenario‐1 (on 17 and 20 February 2018) and the formation of new plasmapause by interchange motion with scenario‐2 (on 22 February 2018 ...

Helical Magnetic Field in a Massive Protostellar Jet

The Astrophysical Journal Letters
Highly collimated outflows (jets) are observed across a wide range of astrophysical systems involving the accretion of material onto central objects, from supermassive black holes in active galaxies to proto-brown dwarfs and stellar-mass black holes ...

Measurement of the plasma astrophysical S factor for the 3He(D, p)4He reaction in exploding molecular clusters [PDF]

, 2013
The plasma astrophysical S factor for the 3He(D, p)4He fusion reaction was measured for the first time at temperatures of few keV, using the interaction of intense ultrafast laser pulses with molecular deuterium clusters mixed with 3He atoms.

Contour Simulations of Astrophysical Jets [PDF]

Symposium - International Astronomical Union, 1990
We apply the theory of the Kelvin-Helmholtz instabilities to trace the jet's pattern. A certain level of noise is introduced.

The Role of the Magnetic Field Orientation on the Variability of the Martian Topside Ionosphere Using MARSIS‐Mars Express Data

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Mars, without a global dipole magnetic field, has its atmosphere directly exposed to the impinging solar wind, producing a complex interaction due to the remnant crustal magnetic fields, which, especially in the southern hemisphere, have spatially varying strengths and inclinations. “Mini‐magnetospheres” generated over the strong crustal field

Observation of energetic protons trapped in laboratory magnetic-tower jets

New Journal of Physics, 2013
Preliminary results of the self-emission of charged particles from magnetically driven plasma jets has been investigated. The jets were launched and driven by a toroidal magnetic field generated by introducing a  ∼ 1.4 MA, 250 ns electrical current pulse

Searches for IceCube neutrinos from blazar flares using correlations with gamma-ray lightcurves [PDF]

EPJ Web of Conferences, 2019
Blazars have long been considered as accelerator candidates for cosmic rays. In such a scenario, hadronic interactions in the jet would produce neutrinos and gamma rays.

Jets from compact objects [PDF]

arXiv, 2000
Some topics in the theory of jets are reviewed. These include jet precession, unconfined jets, the origin of knots, the internal shock model as a unifying theme from protostellar jets to Gamma-ray bursts, relations between the Blandford-Znajek and MHD disk-wind models, and jet collimation in magnetic acceleration models.

Formation and collimation of relativistic MHD jets - simulations and radio maps

, 2013
We present results of magnetohydrodynamic (MHD) simulations of jet formation and propagation, discussing a variety of astrophysical setups. In the first approach we consider simulations of relativistic MHD jet formation, considering jets launched from ...

Coronae on Venus: An Updated Global Database and Insights Into Morphology, Spatial Distribution, Geological Setting, and Lithospheric Properties

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Venus' surface hosts many volcanic and tectonic features, among which coronae are widespread. Despite their inferred significance for Venus' geodynamics, existing corona databases have been incomplete and/or inaccessible. Here, we present an updated database of coronae, which integrates and validates existing data sets while incorporating new ...
