Evolution of Force‐Free Magnetic Structure in the Dayside Ionosphere of Mars

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Magnetic fields measured in the ionosphere of Mars by the magnetometers onboard the Mars Atmosphere and Volatile EvolutioN (MAVEN) and the Mars Global Surveyor (MGS) spacecraft display a wide range of spatial scales, ranging from global to small‐scale.

Effects of Fine Spectral Structure of Chorus Emissions on Nonlinear Scattering and Acceleration of Radiation Belt Electrons

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Whistler‐mode chorus waves play a crucial role in accelerating electrons in Earth's outer radiation belt to relativistic and ultrarelativistic energies. While this electron evolution is typically modeled using a diffusion approximation for scattering, high‐amplitude chorus waves induce nonlinear resonant effects that challenge this approach on

Limits on the Efficacy of Wave‐Particle Interaction on the Energization and Transport of Atomic and Molecular Heavy Ionospheric Ions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Ionospheric molecular ions, such as N2+ ${\mathrm{N}}_{2}^{+}$, NO+, and O2+ ${\mathrm{O}}_{2}^{+}$, have been observed in Earth's high‐altitude ionosphere and the magnetosphere by several spacecraft missions. Their presence not only indicates that they obtain sufficient energy through effective energization mechanisms, predominantly during ...

Spacecraft Discharge Time Constants Determined From Electron‐Flux Suppression During Sounding‐Radar Operation at Mars

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Spacecraft discharge time constants are calculated from measurements of electron differential flux before and during operation of an ionospheric sounding radar. Determining these time constants provides insight into how the operation of a sounding radar affects the surrounding plasma's interaction with the spacecraft.
