Abstract
We study boson star configurations with generic, but not nontopological, se lf-interaction terms. When compared with the usual lambda\psi\(4) potential , similar results for masses and number of particles appear. However, chang es are noticed in the order of a few percent of the star mass. We explore, using catastrophe theory, the stability properties of the configurations an d look for possible observational outputs that may differentiate one model from the other: gravitational redshifts, rotation curves of accreted partic les, and lensing phenomena are computed for our new cases.
