6. Collapse and dispersal of a homogeneous spin fluid in Einstein–Cartan theory / Hashemi, M. ; Jalalzadeh, S. ; Ziaie, A. H.
In the present work, we revisit the process of gravitational collapse of a spherically symmetric homogeneous dust fluid which is described by the Oppenheimer–Snyder (OS) model (Oppenheimer and Snyder in Phys Rev D 56:455, 1939 ). [...]
