Bose-Einstein condensation in compact astrophysical objects — •Christine Gruber1 and Axel Pelster2 — 1Fachbereich Physik, Freie Universität Berlin, Germany — 2Fachbereich Physik, Technische Universität Kaiserslautern, Germany
We discuss the possible occurrence of Bose-Einstein condensates (BECs) in astrophysical contexts, i.e. in compact objects such as neutron stars and white dwarfs. As unlikely as it may seem, conditions in such environments allow for the formation of BECs due to a favorable combination of temperature and density. To this end it is of interest to investigate the condensation of bosonic particles under the influence of gravitational interactions in the framework of a Hartree-Fock theory. Results can be compared to observations through the predicted density profiles and masses of the objects.
