… stars due to the formation of Cooper pairs among the superfluid neutrons. To this end we study the condensation of bosonic … We consider a finite-temperature scenario, generalizing …
… In Newtonian approximation we also consider stars at finitetemperature, in which case the bosons are no longer fully condensed. Section 3 discusses several models for bosonstars in …
… model at zero temperature and magnetic field gives stars with maximum masses … finite temperature on BECS models. We will consider a naked star fully composed of interacting bosons. …
… Bosonstars are gravitationally … stability criteria for fluid stars. With this in mind, I investigate the dynamical instability of bosonstars against chargeconserving, small radial perturbations. …

… The bosonstars we consider can be viewed as zero-temperature, ground-state, Bose-Einstein condensates, with enormous occupation numbers, so that the stellar material is described …
… Instead, if constructed larger than a galaxy, could a bosonstar serve as the dark matter halo … to charged bosonstars and fermion-bosonstars. Rotating bosonstars are found to have an …
… bosonstars account for this non-baryonic part of dark matter [17], [18], [19]. Bosonstars are … –0) instead of electromagnetic fields, ie spin–1 bosons. If scalar fields exist in nature, such …
