JWST/MIRI Study of the Enigmatic Mid-infrared Rings in the Planetary Nebula NGC 1514
The Astronomical JournalWhile NGC 1514 is an elliptical, but complex, planetary nebula at optical wavelengths, it was discovered to have a pair of infrared-bright, axisymmetric rings contained within its faint outer shell during the course of the Wide-field Infrared Survey ...

The Open Journal of AstrophysicsWe conduct three-dimensional hydrodynamical simulations of jets launched into a dense shell, reproducing two rings in a bipolar structure that resemble the two dusty rings of the planetary nebula (PN) NGC 1514.

Planetary formation and early phases
Comptes Rendus. Physique, 2023 Planets form in proto-planetary disks. In this review, we describe the structure and properties of such disks, and the various phenomenons that lead to the final product: a planetary system. First, micrometre dust settles and coagulates.

Simulating Secondary Electron and Ion Emission from the Cassini Spacecraft in Saturn’s Ionosphere
The Planetary Science Journal, 2023 The Cassini spacecraft’s Grand Finale flybys through Saturn’s ionosphere provided unprecedented insight into the composition and dynamics of the gas giant’s upper atmosphere and a novel and complex spacecraft–plasma interaction.
