68 Conclusions Understanding the evolution of stars and galaxies using chemical elements is a degenerate process, and the stellar models are the foundation. WFIRST and microlensing can constrain the mass function of neutron stars and black holes. The field of chemical evolution allows to create a more coherent picture of how stars and galaxies evolve and interact. Any additional constraint help in getting closer to this big picture.
