Small-scale Field-aligned Currents in the Magnetopause Boundary Layer

open access: yesThe Astrophysical Journal
Based on high-resolution measurements from the Magnetospheric Multiscale mission from 2015 May to 2018 June, we statistically investigate the properties of small-scale field-aligned currents (SFACs) in the magnetopause boundary layer.

A mechanism for bursty radio emission in planetary magnetospheres

open access: yes, 1990
Bursty radio emissions are often observed from the polar magnetospheres of the Earth, Jupiter, Saturn, and Uranus in addition to the smooth radio emissions commonly detected.

Backscattering of Ions Impacting Ganymede’s Surface as a Source for Energetic Neutral Atoms

open access: yesThe Astrophysical Journal Letters
Jupiter’s largest moon Ganymede has its own intrinsic magnetic field, which forms a magnetosphere that is embedded within Jupiter’s corotating magnetospheric plasma.

In situ, Surface-deployed Distributed Instruments for Planetary Science: Scientific Opportunities and Technology Feasibility

open access: yesThe Planetary Science Journal
In this paper, we assess the scientific promise and technology feasibility of in situ distributed instruments for planetary surface and atmospheric science. A distributed instrument is an instrument designed to collect spatially and temporally correlated

Frequency Characteristics of Magnetosonic Waves Driven by Hot Ring-Beam Protons

open access: yesThe Astrophysical Journal
Magnetosonic (MS) waves can be generated by energetic ring-beam protons, appearing as harmonics near the local proton cyclotron frequency, in the planetary ionospheres/magnetospheres.

Effects of the 2007 Martian Global Dust Storm on Boundary Positions in the Induced Magnetosphere

open access: yesThe Planetary Science Journal
Mars's magnetosphere is a sensitive system, varying due to external and internal factors, such as solar wind conditions and crustal magnetic fields.

Imaging polarimetry of planetary and proto-planetary nebulae [PDF]

open access: yes, 1997
Optical imaging polarimetry has been performed on a small sample of objects which are associated with that stage of stellar evolution occurring between the Asymptotic Giant Branch and full Planetary Nebula. Three such systems are considered, specifically,

Wave Responses to Magnetosheath Boundary Motion at Saturn: Mirror Modes and Electromagnetic Ion Cyclotron Waves

open access: yesThe Astrophysical Journal
Saturn’s magnetosheath provides a natural laboratory for studying the generation and evolution of low-frequency plasma waves that play a key role in regulating temperature anisotropy and mediating wave–particle interactions.

Relativistic Electron Acceleration and the “Ankle” Spectral Feature in Earth’s Magnetotail Reconnection

open access: yesThe Astrophysical Journal Letters
Electrons are accelerated to high, nonthermal energies during explosive energy-release events in space, such as magnetic reconnection. However, the properties and acceleration mechanisms of relativistic electrons directly associated with the reconnection
