Reflex instabilities II: The reflex motion of the central object drives at least seven instabilities in accretion discs
Nathan Magnan, Michel Tagger, Clément Baruteau +3
This series of papers studies the stability of accretion discs to the reflex motion of the central object under the gravitational pull of the disc itself. In this second paper, we…
Reflex instabilities I: Boundaries makes grid-based disc simulations frame-dependent
Nathan Magnan, Michel Tagger, Clément Baruteau +4
If the mass distribution within an accretion disc is asymmetric, it will exert a gravitational pull on its central object. The central object must then move away from the origin of…
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…
