Current Events at Saturn: Ring–Planet Electromagnetic Coupling
The Planetary Science JournalThis study presents a synthesized analysis of in situ and ground-based observations to investigate electromagnetic coupling between Saturn and its rings. During the Cassini Grand Finale, the magnetometer detected gradients in the azimuthal magnetic field

The Case for Future Gravity Science Investigations at Saturn with a Planetary Orbiter
The Planetary Science Journal, 2023 The next phase in the robotic exploration of the Saturnian system will target unresolved questions about the gas giant’s atmosphere, interior, magnetosphere, and rings that were left open by investigations on board the Cassini mission.

UTM, a universal simulator for lightcurves of transiting systems [PDF]
, 2008 The Universal Transit Modeller (UTM) is a light-curve simulator for all kinds of transiting or eclipsing configurations between arbitrary numbers of several types of objects, which may be stars, planets, planetary moons, and planetary rings. Applications

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Simulating planet migration in globally evolving disks [PDF]
, 2006 Numerical simulations of planet-disk interactions are usually performed with hydro-codes that -- because they consider only an annulus of the disk, over a 2D grid -- can not take into account the global evolution of the disk.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

A Survey of Cassini Images of Spokes in Saturn’s Rings: Unusual Spoke Types and Seasonal Trends
The Planetary Science JournalSpokes are localized clouds of fine particles that appear over the outer part of Saturn's B ring. Over the course of the Cassini mission, the Imaging Science Subsystem obtained over 20,000 images of the outer B ring, providing the most comprehensive data
