A Multifrequency Global View of Callisto’s Thermal Properties from ALMA

The Planetary Science Journal
We present thermal observations of Callisto’s leading and trailing hemispheres obtained using the Atacama Large Millimeter/submillimeter Array (ALMA) at 0.87 mm (343 GHz), 1.3 mm (233 GHz), and 3 mm (97 GHz).

Revealing Callisto’s Near-subsurface Thermophysical Properties with ALMA Calibration Data

The Planetary Science Journal
Thermal images at different wavelengths probe varying subsurface depths of planetary bodies and therefore can inform us about their compositions, thermophysical properties, and impact histories.

A virtual tour of the Galilean Satellites [PDF]

Proceedings of the International Astronomical Union, 2010
Galileo's imagination was quick to comprehend the importance of the 4 starry objects he observed near Jupiter in January 1610, not only for himself as a scientist but for our common understanding of the place of the Earth and our species in the cosmos.

A High-precision Dynamical Model of Callisto: Incorporating Rotation Effects within Multilayer Internal Structure Models

The Astrophysical Journal
China is planning to launch the “Tianwen-4” mission around the year 2030, with its aim being the exploration of Jupiter and its moon, Callisto. Within the realm of deep space exploration, the accuracy of ephemerides is of great importance.

Impact of Jupiter’s Heating and Self-shadowing on the Jovian Circumplanetary Disk Structure

The Planetary Science Journal
Deciphering the structure of the circumplanetary disk (CPD) that surrounded Jupiter at the end of its formation is key to understanding how the Galilean moons formed.

On the Theory of the Galilean Satellites of Jupiter [PDF]

Symposium - International Astronomical Union, 1974
In this communication the main equations for the variables: radius vector, longitude,PandQ(variables built from Laplace's perihelium first integral) are given in closed form. These equations are used for deriving the equations of a second-order theory.

Laboratory Investigation of CO2-driven Enhancement of Radiolytic H2O2 on Europa and Other Icy Moons

The Planetary Science Journal
Observations of Europa’s leading hemisphere reveal elevated H _2 O _2 in the warmer, low-latitude chaos terrains compared to the colder, polar regions.
