The LISA Astrophysics "Disc-IMRI" Code Comparison Project: Intermediate-Mass-Ratio Binaries in AGN-Like Discs
Andrea Derdzinski, Alexander J. Dittmann, Alessia Franchini +16
Upcoming space-based gravitational wave detectors such as LISA, the Laser Interferometer Space Antenna, will be sensitive to extreme- and intermediate-mass-ratio inspirals (EMRIs a…
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 the formation of multiple dust-trapping rings in the inner Solar system
E. Lega, A. Morbidelli, F. Masset +1
Isotopic properties of meteorites provide evidence that multiple dust trap or pressure bumps had to form and persist in the inner Solar System on a timescale of millions of years.…
Dust-void evolution driven by turbulent dust flux can induce runaway migration of Earth-mass planets
R. O. Chametla, O. Chrenko, F. S. Masset +2
Torques from asymmetric dust structures (so-called dust-void and filamentary structures) formed around low-mass planets embedded in a non turbulent dust-gas disk can exceed the tor…
Pebble-driven migration of low-mass planets in the 2D regime of pebble accretion
O. Chrenko, R. O. Chametla, F. S. Masset +2
<Context> Pebbles drifting past a disk-embedded low-mass planet develop asymmetries in their distribution and exert a substantial gravitational torque on the planet, thus modifying…
