Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

On the Migration of the Galilean Satellites [PDF]
, 2013 The migration of the Galilean satellites during formation due to interactions with the circumjovian disk is studied. In the gas-starved disk model proposed by Canup & Ward (2002, 2006), the Galilean satellites are the last generation of satellites ...

A semi-analytical model of the Galilean satellites’ dynamics
, 2018 The Galilean satellites’ dynamics has been studied extensively during the last century. In the past it was common to use analytical expansions in order to get simple models to integrate, but with the new generation of computers it became prevalent the ...

Philosophy and Phenomenological Research, Volume 113, Issue 1, Page 134-152, July 2026.ABSTRACT Determinism is (roughly) the thesis that the past determines the future. But efforts to define it precisely have exposed deep methodological disagreements. Standard possible‐worlds formulations of determinism presuppose an “agreement” relation between worlds, but this relation can be understood in multiple ways, none of which is particularly ...

New Estimation of Usually Neglected Forces Acting on Galilean System
, 2001 International audienceWe studied small perturbations acting on Galilean satellites. Most of them are still not computed in the analytical theories and could probably improve the ephemeris of these satellites which are outside the precision of the ...

Callisto’s Nonresonant Orbit as an Outcome of Circum-Jovian Disk Substructure
The Astrophysical JournalThe Galilean moons of Io, Europa, and Ganymede exhibit a 4:2:1 commensurability in their mean motions, a configuration known as the Laplace resonance. The prevailing view for the origin of this three-body resonance involves the convergent migration of ...

Predictions of the mutual events of the Galilean satellites of Jupiter occurring in 2009–2010
, 2007 Aims. Mutual occultations and eclipses of the Galilean satellites of Jupiter will occur in 2009–2010. This paper provides predictions of these events as well as useful information for their observations.
