Cosmological expansion and local systems: a Lemaître-Tolman-Bondi
model    [PDF]

Ivana Bochicchio, Valerio Faraoni

We propose a Lema\^{i}tre-Tolman-Bondi system mimicking a two-body system to address the problem of the cosmological expansion versus local dynamics. This system is strongly bound but participates in the cosmic expansion and is exactly comoving with the cosmic substratum.
