Two dimensional hybrid simulations of small scale obstacles in the solar wind [PDF]

The structure and dynamics of the solar wind interaction with two small scale obstacles (of the order of a pickup ion gyroradius) is examined. These are a comet, comparable to Grigg-Skjellerup, and a weakly ionospheric planet.

Ion dynamics in magnetosonic shock front

Solar-Terrestrial Physics, 2018
I address the ion dynamics at the front of magnetosonic shocks moving at different angles θ to the magnetic field vector. I employ a shock discontinuity model in which the ramp potential difference is taken into account.

Effects of Hot Oxygen Corona on Ion Escape From Venus‐Like Planets

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Due to the lack of a significant planetary magnetic field, the upper atmospheres of Venus‐like planets interact directly with the stellar wind. Therefore, thermal atomic oxygen in the thermosphere and hot oxygen in the corona produced by non‐thermal processes in the upper atmosphere act as a source of ion pickup loss.

Detection of m/q=2 pickup ions in the plasma environment of the Moon: The trace of exospheric H-2(+) [PDF]

, 2011
The Solar Wind Ion Detectors (SWIDs) on the Chang' E-1 spacecraft, while orbiting the Moon, occasionally observed two continuous flux peaks with energies not exceeding 8 and 4 times that of the prevailing solar wind proton energy.

Solar Wind Transverse Deflection Upstream of the Martian Bow Shock: Evidence from MAVEN Observations

The Astrophysical Journal
The interaction between the solar wind and the Martian upper atmosphere involves mass loading by newly created pickup ions (PUIs). Accordingly, these PUIs can modify the solar wind flow upstream of the Martian bow shock through momentum exchange.

Oxygen Exosphere of Mars: Evidence from Pickup Ions Measured by MAVEN [PDF]

, 2016
Mars possesses a hot oxygen exosphere that extends out to several Martian radii. The main source for populating this extended exosphere is the dissociative recombination of molecular oxygen ions with electrons in the Mars ionosphere.

Evidence for a Mixture of Mirror Mode and Electromagnetic Ion Cyclotron Waves in the Martian Magnetosheath

The Astrophysical Journal
Electromagnetic ion cyclotron (EMIC) and mirror-mode (MM) waves are widely observed in terrestrial and other planetary magnetosheaths. Even though linear theory supports that EMIC and MM waves may grow at comparable rates under suitable plasma conditions,

PUI Acceleration at an Oblique Heliospheric Termination Shock: 2D Hybrid Kinetic Simulation

The Astrophysical Journal Letters
We investigate the acceleration of pickup ions (PUIs) at an oblique heliospheric termination shock (HTS) using 2D kinetic hybrid simulations. The background magnetic field, B _0 , is set in-plane and makes an angle of Θ _Bn  = 50° with respect to the ...

Interstellar helium pickup ion flux variations observed with SOHO/CELIAS [PDF]

, 2005
Interstellar pickup ions are formed when neutral atoms freely enter the heliosphere and are subsequently ionized. Once these particles are charged they become a component of the interplanetary plasma and are transported outward with the solar wind (SW ...
