Can Jupiter’s Atmospheric Metallicity Be Different from the Deep Interior?

open access: yesThe Astrophysical Journal
Updated formation and structure models of Jupiter predict a metal-poor envelope. This is at odds with the two to three times solar metallicity measured by the Galileo probe. Additionally, Juno data imply that water and ammonia are enriched.

STRUCTURE AND DYNAMICS OF PLANETARY MAGNETOSPHERES

open access: yes, 2022
The interactions between the ambient plasmas and the objects of the Solar System result in variable exchanges both in time and space of mass, momentum and energy within different types of magnetospheres. The characterization of the sources, the general circulation and the losses of the magnetospheric plasmas as well as the identification of the ...

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

open access: yesAdvanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...
