Eos, Transactions American Geophysical Union, 2008 Life used to be simple for ring scientists. Since the time of Galileo, anyone with even the most basic telescope could see that Saturn was the only planet with rings. Saturn's ring system is clearly bright, broad, and bland. James Clerk Maxwell proved that the rings could not be solid, and basic spectroscopy showed that they are composed primarily of ...

Planetary Rings and Other Astrophysical Disks [PDF]
, 2018 This chapter explores the physics shared by planetary rings and the various disks that populate the Universe. It begins with an observational overview, ranging from protoplanetary disks to spiral galaxies, and then compares and contrasts these astrophysical disks with the rings of the Solar System. Emphasis is placed on fundamental physics and dynamics,

A Symplectic Integrator for Hill's Equations
, 2009 Hill's equations are an approximation that is useful in a number of areas of astrophysics including planetary rings and planetesimal disks. We derive a symplectic method for integrating Hill's equations based on a generalized leapfrog.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space
Advanced Materials, EarlyView.In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

On the Detection of Exorings in Reflected Light with JWST NIRCam
The Astronomical JournalWhen directly imaging a cold-giant exoplanet hosting a ring system, the reflected light from the rings can outshine the planet’s thermal emission and reflected light in the near-infrared.

Saturn and its Rings: Four Centuries of Imperfect Amodal Completion
i-Perception, 2019 The planet Saturn is a familiar image for us, but it presents perceptual peculiarities that impeded the discovery of its structure and which can still be misleading today.
