1 the First Compact Objects in the Mond Model ∗

We trace the evolution of a spherically symmetric density perturbation in the MOdified Newtonian Dynamics (MOND) model. The background cosmological model is a Λ-dominated, low-Ωb Friedmann model with no Cold Dark Matter. We include thermal processes and non-equilibrium chemical evolution of the collapsing gas. We find that the first density perturbations which collapse to form luminous objects have mass ∼ 105M⊙. The time of the final collapse of these objects depends mainly on the value of the MOND acceleration a0 and also on the baryon density Ωb. For the ”standard” value a0 = 1.2 × 10 cm/s the collapse starts at redshift z ∼ 160 for Ωb = 0.05 and z ∼ 110 for Ωb = 0.02.
