High‐Latitude Off‐Great Circle Propagation Associated With the Solar Terminator
Radio Science, Volume 59, Issue 5, May 2024.Abstract Large‐scale ionospheric gradients associated with the solar terminator can deflect high frequency (HF) radio waves to off‐great circle paths during the morning and evening, negatively impacting technologies reliant on HF radio wave propagation.

Statistical Analysis of Off‐Great Circle Radio Wave Propagation in the Polar Cap
Radio Science, Volume 59, Issue 4, April 2024.Abstract High latitude ionospheric density structures such as polar cap patches and arcs are capable of deflecting high frequency (HF) radio waves to off‐great circle paths, and are likely detrimental to technologies dependent on HF radio propagation.

Journal of Geophysical Research: Planets, Volume 129, Issue 3, March 2024.Abstract Toroidal atmospheres and exospheres characterized at exoplanets may be fueled by volcanically active exomoons, often referred to as exo‐Ios. We study the neutral outgassing and volatile evolution of a close‐orbiting, evaporating satellite at eight candidate exoplanet‐exomoon systems WASP‐49,‐96,‐69,‐17 b, XO‐2N b, HAT‐P‐1 b, HD‐189733 b, and ...
