Planetesimal formation via the streaming instability persists under turbulence driven by magnetorotational instability
The episode discusses a paper showing that planet-building blocks can form via streaming instability even when protoplanetary disks are turbulent due to magnetorotational instability. Hosts discuss how non-ideal MHD effects and localized gas pressure gradients allow this process to persist, suggesting future observations should look for localized density clumps.
