Geophysical Monograph Series, Page i-xiv., 2021 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.

Perspective on Energetic and Thermal Atmospheric Photoelectrons
Frontiers 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.

Comparison of terrestrial and Martian TEC at dawn and dusk during solstices
Earth, 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.

Ion Loss within a Reconnection Exhaust near Mars: MAVEN Observations
The 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.

Oscillation of the Ionosphere at Planetary‐Wave Periods
Journal of Geophysical Research: Space Physics, 2018 AbstractF‐region ionospheric oscillations at planetary‐wave (PW) periods (2–20 days) are investigated, with primary focus on those oscillations transmitted to the ionosphere by PW modulation of the vertically propagating tidal spectrum. Tidal effects are isolated by specifically designed numerical experiments performed with the National Center for ...

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

Species-dependent ion escape on Titan
Earth and Planetary Physics, 2019 Cassini observations over the past ten years have revealed that Titan possesses a chemically complex ionosphere. In this study, we investigate the relative contributions of different ion species to the total ion escape on Titan, by dividing all ion ...
