The reflex instability: exponential growth of a large-scale mode in astrophysical discs
Aurélien Crida, Clément Baruteau, Jean-François Gonzalez +5
We report the finding of a linear, non-axisymmetric, global instability in gas discs around stars, which may be relevant to other astrophysical discs. It takes the form of an …
On inertial forces (indirect terms) in problems with a central body
Aurélien Crida, Clément Baruteau, Philippine Griveaud +14
Gravitational systems in astrophysics often comprise a body -- the primary -- that far outweights the others, and which is taken as the centre of the reference frame. A fictitious…
The Gaia spectroscopic catalogue of exoplanets and host stars
Patrick de Laverny, Roxanne Ligi, Aurélien Crida +2
Complete, accurate, and precise catalogues of exoplanet host star (EHS) properties are essential to deriving high-quality exoplanet parameters. This paper aims at homogeneously par…
Understanding the formation of Saturn's regular moons in the context of giant planet moons formation scenarios
Michel Blanc, Aurélien Crida, Yuhito Shibaike +7
This article explores the different formation scenarios of the Kronian moons system in the context of a highly dissipative Saturn, with the objective of identifying the most likely…
The Origin and Evolution of Saturn: A Post-Cassini Perspective
Sushil K. Atreya, Aurélien Crida, Tristan Guillot +5
The Saturn System has been studied in detail by the Cassini-Huygens Mission. A major thrust of those investigations has been to understand how Saturn formed and evolved and to plac…
