A New Tool for Understanding the Solar Wind–Venus Interaction: Three-dimensional Multifluid MHD Model

open access: yesThe Astrophysical Journal, 2023
In this paper, we present a new tool to investigate the interaction of the solar wind with Venus with the approach of a global multifluid magnetohydrodynamics (MHD) model. The continuity, momentum, and energy equations for H ^+ , O ^+ , ${{\rm{O}}}_{2}^{+

Characteristic Timescales for the Dayside Martian Ionosphere: Chemistry, Diffusion, and Magnetization

open access: yesThe Astronomical Journal, 2023
Different boundaries could be defined in a planetary ionosphere where the dominant process in function switches from one to the other. Identifying these boundaries and understanding their variations are hence crucial for disentangling the complexity of ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Comparison of terrestrial and Martian TEC at dawn and dusk during solstices

open access: yesEarth, Planets and Space, 2020
This paper used the similarities between the ionospheres on Mars and Earth, the most similar of the terrestrial planets, to examine the relative importance of photochemical and transport processes at dawn and dusk.

Perspective on Energetic and Thermal Atmospheric Photoelectrons

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Atmospheric photoelectrons are central to the production of planetary ionospheres. They are created by photoionization of the neutral planetary atmosphere by solar EUV and soft X-ray irradiance.

Ion Loss within a Reconnection Exhaust near Mars: MAVEN Observations

open access: yesThe Astrophysical Journal, 2023
We present observations from Mars Atmosphere and Volatile EvolutioN of a reconnection exhaust, which was probably not ongoing, in the Martian magnetosheath. The reconnection jet with abundant heavy ions is directed outward to space.

Simulating Secondary Electron and Ion Emission from the Cassini Spacecraft in Saturn’s Ionosphere

open access: yesThe Planetary Science Journal, 2023
The Cassini spacecraft’s Grand Finale flybys through Saturn’s ionosphere provided unprecedented insight into the composition and dynamics of the gas giant’s upper atmosphere and a novel and complex spacecraft–plasma interaction.

Bond-forming reactions of N22+ with C2H4, C2H6, C3H4 and C3H6

open access: yes, 2015
Mass spectrometry, coupled with position-sensitive coincidence detection, has been used to investigate the reactions of N22+ with various small hydrocarbon molecules (C2H4, C2H6, C3H4, c-C3H6 and n-C3H6) at collision energies below 10 eV in the centre-of-

Variability of the Martian ionosphere from the MAVEN Radio Occultation Science Experiment

open access: yesEarth and Planetary Physics, 2019
The Martian ionosphere is produced by a number of controlling processes, including solar extreme ultraviolet radiation (EUV) and X-ray ionization, impact ionization by precipitating electrons, and day-to-night transport.
