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 effect of dust on vortices II: Streaming instabilities
Nathan Magnan, Henrik Nils Latter
One of the main questions in planet formation theory is how to cross the metre-scale barrier. In this two-part series, we assess the merits of vortex-based theories by investigatin…
The effect of dust on vortices I: Laminar models
Nathan Magnan, Henrik Nils Latter
One of the main questions regarding planet formation is how to cross the metre-scale barrier. Several theories rely on the formation of dust clumps dense enough to collapse under t…
The physical mechanism of the streaming instability
Nathan Magnan, Tobias Heinemann, Henrik N. Latter
The main hurdle of planet formation theory is the metre-scale barrier. One of the most promising ways to overcome it is via the streaming instability (SI). Unfortunately, the mecha…
A physical picture for the acoustic resonant drag instability
Nathan Magnan, Tobias Heinemann, Henrik N. Latter
Mixtures of gas and dust are pervasive in the universe, from AGN and molecular clouds to proto-planetary discs. When the two species drift relative to each other, a large class of…
Orbital alignment and mass segregation in galactic nuclei via vector resonant relaxation
Nathan Magnan, Jean-Baptiste Fouvry, Christophe Pichon +1
Supermassive black holes dominate the gravitational potential in galactic nuclei. In these dense environments, stars follow nearly Keplerian orbits and see their orbital planes rel…
