Not all cores are equal: Phase-space origins of dynamical friction, stalling and buoyancy
The episode discusses a paper titled "Not all cores are equal: Phase-space origins of dynamical friction, stalling and buoyancy." Hosts discuss how stalling occurs when a perturber hits a plateau in dynamical friction, while buoyancy involves an internal instability pushing the perturber away. The study emphasizes that the shape of the distribution function, not just core size, determines these outcomes.
