Statistical Study of Short Large‐Amplitude Magnetic Structures at Mars Observed by MAVEN

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We present a statistical study of Short Large‐Amplitude Magnetic Structures (SLAMS) in the Martian foreshock using data from the Mars Atmosphere and Volatile Evolution (MAVEN) mission between 01 January 2015 and 31 December 2019. We have identified 21,008 SLAMS during this time interval and statistical results are presented on the SLAMS ...

Polarization Measurements and Source Locations of Saturn Electrostatic Discharges During the Voyager Era

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract A Saturn Electrostatic Discharge or SED is an intense electromagnetic impulse induced by Saturn lightning, which escapes into space through the magnetoplasma of the ionosphere. Since previous SED polarizations from Voyager data are inconclusive, this polarization study is the first which properly considers the characteristics of the Voyager ...

A Simplified Method for Calculating Surface Area of Mammalian Erythrocytes

Methods and Protocols
Knowledge of the geometric quantities of the erythrocyte is useful in several physiological studies, both for zoologists and veterinarians. While the diameter and volume (MCV) are easily obtained from observations of blood smears and complete blood count,

Modeling of voltaic pile surface formation using current-carrying cassini ovals

Engineering Science and Technology, an International Journal, 2019
In this paper, the possibility of increasing the surface of an electric discharge in ignition devices of a working mixture of internal combustion engines is analyzed. There are results of simulating the change in the shape of the lower end of the spark plug central electrode from the flat to conductive Cassini ovals.

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

The Cycles and Dynamical Properties of Convective Outbreaks in Jupiter's Highest Speed Jet From a 55‐Year Study

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Jupiter's most intense jet at planetographic latitude 23.7°N experiences vigorous planetary‐scale disturbances. The onset consists of the outbreak of 1–3 bright clouds of convective origin developing turbulent plumes. Observed events between 1970 and 2025 shows a cycle of activity with a period in the range of 3.8–5.1 yrs interrupted between ...

Atmospheric Ion‐Neutral Coupling as a Potential Driver for Saturn's Magnetospheric Antisunward Electric Field

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

Rapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

The Origin of Jupiter's Great Red Spot

Geophysical Research Letters
Jupiter's Great Red Spot (GRS) is the largest and longest‐lived known vortex of all solar system planets but its lifetime is debated and its formation mechanism remains hidden. G. D.

Cassini-oval Description of the Energy Balance at Scission During 235U(nth, f)

Physics Procedia, 2012
AbstractFor a detailed description of the excitation energy of the fission fragments, that is used to evaporate neutrons and emit γ-rays, realistic nuclear shapes at scission are necessary. It is shown that the nuclear shapes around the scission point, along the main fission mode, are well described by Cassini ovals with only two parameters: α ...
