On dust–gas gravitational instabilities in protoplanetary discs

In protoplanetary discs the aerodynamical friction between particles and gas induces a variety of instabilities that facilitate planet formation. Of these we examine the so-called 'secular gravitational instability' (SGI) in the two-fluid approximation, deriving analytical expressions for...
