Merton Davies (1917-2001) [PDF]
, 2001 Merton Davies passed away unexpectedly in April at age 83 due to complications from surgery. He will be remembered for establishing the prime meridian for essentially every solid planet in the solar system with the exception of Earth and Pluto.

Martian Crustal Magnetic Field Effects on the Ionospheric Main Peak
The Astrophysical JournalPlanetary magnetic fields can affect ionospheric plasma transport and coupling with the solar wind. In contrast to the terrestrial global magnetic field, there are only weaker and sporadic crustal magnetic fields on Mars. Many studies have indicated that

Experimental Study of the Response of Sheared E × B Flow to Varying Ion–Neutral Collisions
The Astrophysical Journal, 2023 Partially ionized plasma is a common occurrence in astrophysical and space environments. The emergence and development of plasma instabilities are significantly impacted by the inelastic collisions between the ions and neutrals in the partially ionized ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Locally generated fast magnetosonic (local MS) waves in the Martian ionosphere have been reported recently, which are different from the solar wind‐driven MS waves. However, their effects on particle scattering have not been reported yet. This study pioneers the investigation of electron, proton, and oxygen atomic ion scattering induced by ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Interactions of solar wind dynamic pressure (SWDP) discontinuities with Earth's magnetosphere cause geomagnetic Sudden Commencements (SCs). Typically, positive/negative SCs occur at low latitudes due to enhancements/reductions in SWDP.

Occultations of Astrophysical Radio Sources as Probes of Planetary Environments: A Case Study of Jupiter and Possible Applications to Exoplanets [PDF]
, 2017 Properties of planetary atmospheres, ionospheres, and magnetospheres are difficult to measure from Earth. Radio occultations are a common method for measuring these properties, but they traditionally rely on radio transmissions from a spacecraft near the
