The modulation of SiO maser polarization by Jovian planets

, 2008
Searching for planets in the atmosphere of AGB stars is difficult, due to confusion with the stellar wind and pulsations. The aim here is to provide a complementary strategy for planet search in such a dense environment.

Mapping a Carrington Storm

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract A map is presented of median 1‐min‐resolution peak geoelectric‐field strength across the United States as would be induced by magnetic storms as intense as the 2 September 1859 Carrington storm. The map is constructed from two data sets: Magnetometer time series from 22 ground‐based observatories recording 40 magnetic storms, and surface ...

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-

Twisted magnetosphere with quadrupolar fields in the exterior of a neutron star

, 2018
The magnetar magnetosphere is gradually twisted by shearing from footpoint motion, and stored magnetic energy also increases at the same time. When a state exceeds a threshold, flares/outbursts manifest themselves as a result of a catastrophic transition.

Electron Energization by Dispersive Alfvén Waves in the Cusp

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The propagation of kinetic Alfvén waves (assumed sourced from intermittent dayside reconnection) is investigated with a gyrofluid‐kinetic electron model compared with Cluster observations. These observations reveal electron distributions that are preferentially field‐aligned or field‐opposed, with signatures that are unidirectional or ...

Kinetic-scale magnetic turbulence and finite Larmor radius effects at Mercury

, 2011
We use a nonstationary generalization of the higher-order structure function technique to investigate statistical properties of the magnetic field fluctuations recorded by MESSENGER spacecraft during its first flyby (01/14/2008) through the near Mercury ...

Direct Radiation Belt Injections and Their Auroral Counterparts

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present a case study of a moderate geomagnetic storm, which exhibits an abrupt relativistic enhancement in the heart of the radiation belt accompanied by low‐latitude purple auroral emission. The relativistic enhancement occurs on a timescale of tens of minutes and reaches MeV energies deep within the inner magnetosphere. The enhancement is

Solar wind entry into the high-latitude terrestrial magnetosphere during geomagnetically quiet times

Nature Communications, 2013
An understanding of the transport of solar wind plasma into and throughout the terrestrial magnetosphere is crucial to space science and space weather. For non-active periods, there is little agreement on where and how plasma entry into the magnetosphere

Extra Zebra Stripes Observed by Macao Science Satellite‐1 in the Inner Radiation Belt

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Zebra stripes, characterized by periodic banded structures in the energy‐L shell spectra of energetic electrons in the Earth's inner radiation belt, are understood to result from the azimuthal drift of electrons perturbed by prompt electric field perturbations.
