A Global Map of Average Electron Densities in the Magnetosphere of Saturn
Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract Measurements from the Cassini Radio and Plasma Wave Science (RPWS) experiment obtained during the entire orbital phase of the Cassini mission around Saturn (13.2 years) are processed into a meridional map of plasma densities, comprising the innermost region of the ring ionosphere, the Enceladus plasma torus, and the outer magnetosphere, up to ...

Stellar Dynamics around Black Holes in Galactic Nuclei [PDF]
, 1998 We classify orbits of stars that are bound to central black holes in galactic nuclei. The stars move under the combined gravitational influences of the black hole and the central star cluster. Within the sphere of influence of the black hole, the orbital

Emission of Energetic Neutral Atoms From Ganymede's Magnetosphere‐Atmosphere Interaction
Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract This study analyzes the emission of energetic neutral atoms (ENAs), generated by charge exchange between energetic protons and Ganymede's atmosphere. We also constrain the observability of such ENAs by an imaging instrument aboard a spacecraft.

Detection of Negative Carbon and Oxygen Pickup Ions From Dust Orbiting Jupiter
Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.Abstract We report on observations of negative carbon and oxygen pickup ions (PUIs) originating from dust orbiting Jupiter. The PUIs are observed at altitudes of a few thousand kilometers (∼4,800–10,200 km) above the 1‐bar level of Jupiter's atmosphere and up to ∼11,000–15,000 km from the equatorial plane, thus providing constraints on the location of ...

Quasi Periodic Oscillations (QPOs) and frequencies in an accretion disk and comparison with the numerical results from non-rotating black hole computed by the GRH code [PDF]
, 2006 The shocked wave created on the accretion disk after different physical phenomena (accretion flows with pressure gradients, star-disk interaction etc.) may be responsible observed Quasi Periodic Oscillations (QPOs) in $X-$ray binaries. We present the set

Circumbinary Chaos: Using Pluto's Newest Moon to Constrain the Masses of Nix & Hydra
, 2012 The Pluto system provides a unique local laboratory for the study of binaries with multiple low mass companions. In this paper, we study the orbital stability of P4, the most recently discovered moon in the Pluto system.
