The Gravitational Field of Deimos

open access: yesIcarus, 1995
Abstract Deimos may be largely uniform in density. We find here the gravitational field of Deimos and its moments of inertia from the moon's shape and an assumed uniform density distribution. From these data we compute the expected orientation. The orientation of the model Deimos relative to Mars agrees with that observed to within the observation ...

The Sesquinary Catastrophe on Deimos Can Reconcile Its Excited Past with Its Dynamically Cool Present

open access: yesThe Planetary Science Journal
The origins of the Martian moons Phobos and Deimos are highly debated, and hypotheses include formation from an impact-generated circum-Martian disk and formation from capture of asteroids.

Assessment of Ionospheric Model Performance Over the US During the Extreme G5 2024 Mother's Day Geomagnetic Storm

open access: yesSpace Weather, Volume 24, Issue 5, May 2026.
Abstract This study evaluates 17 ionospheric models' performance over the Continental United States (CONUS) during the 2024 Mother's Day geomagnetic storm, using ground‐based GNSS Total Electron Content (TEC) and single‐frequency (SF) precise Single Point Positioning (SPP) technique. The storm produced significant positive storm effects during its main
