[en] A simple model to study boson stars is to consider these stellar objects as quantum systems of N identical self-gravitating particles within a non-relativistic framework. Some results
obtained with point-like particles are recalled as well as the validity limits of this model. Approximate analytical calculations are performed using envelope theory for a truncated
Coulomb-like potential simulating a particle size. If the boson mass is sufficiently small, the description of small mass boson stars is possible within non-relativistic formalism. The
mass and radius of these stellar objects are strongly dependent on the value of the truncation parameter.
