Pitch Angle Distributions of Energetic Electrons Near Ganymede: Galileo EPD Measurements

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Galileo flew‐by Ganymede six times between 1996 and 2000. The Energetic Particles Detector (EPD) performed energy resolved, directional electron measurements, and together with the magnetometer data, pitch angle distributions (PADs) could be derived.

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

Cassini-oval description of atomic binding: a new method to evaluate atomic hardness

open access: yes, 2022
This paper reports that the binding process of two heteronuclear atoms can be described by Cassini oval in dynamic form, every molecular state corresponds to one of these graphs. the approach is based on a constraint rule between hardness and deformation of atomic particles, then the critical phenomena of molecular deformation are discovered and the ...

Parametrization of Curves in AutoCAD by the Example of Cassini''s Ovals

open access: yes, 2020
A new approach to the integrated study of descriptive geometry and computer graphics in a higher educational institution on the basis of in-depth study of some topics is proposed. The technique is demonstrated in a practical example devoted to the consideration of the possibility of quick creation and investigation of the properties of Cassini ovals on

Non-Archimedean Brauer Oval (of Cassini) Theorem and Applications

open access: yes
Nica and Sprague [\textit{Am. Math. Mon., 2023}] derived a non-Archimedean version of the Gershgorin disk theorem. We derive a non-Archimedean version of the oval (of Cassini) theorem by Brauer [\textit{Duke Math. J., 1947}] which generalizes the Nica-Sprague disk theorem.

Fixed k-cassini oval results on metric spaces

open access: yes
In this paper, we generalize the well-known Cassini curves to metric spaces by introducing the concept of k-Cassini ovals. We provide various examples of k-Cassini ovals in different metric spaces, accompanied by illustrative shapes. Furthermore, we present the existence and uniqueness theorems for the transformation T : X → X, establishing conditions ...

Kepler's ellipse, Cassini's oval and the trajectory of planets

European Journal of Physics, 2014
Summary: In this article, we discuss the similarities and differences between Kepler's ellipse and Cassini's oval with a small eccentricity. We show that these curves are barely distinguishable when the planetary orbits of our solar system are considered and that, from a numerical viewpoint, it is difficult to decide in favour of one of them.

Kepler ellipse or Cassini oval?

European Journal of Physics, 1994
At the time of Newton, the astronomer J.D. Cassini suggested that the orbit of a planet is a 'Cassini oval'. This idea is re-examined from a geometrical point of view.
