In this paper, we address the implications when a homogeneous dust model is considered for
a scenario of gravitational collapse in the context of Eddington-inspired Born-Infeld (EiBI) theory.
In order to describe the dynamical evolution of the collapse, we present an effective equation,
which constitutes the first order corrections, in EiBI coupling parameter κ, to Einstein's field equations.
The geometry outside the collapsing object is derived by imposing the standard
Darmois-Israel junction conditions at the boundary surface of the dust.
This induces an effective matter source in the outer region
which gives rise to a non-singular, non-Schwarzschild geometry at the final state of the collapse.
For this exterior geometry, we find the threshold of mass for the formation of the black hole. This provides a cut-off over κ as |κ|=5.1×10−97 kg−1·m3.
