Equatorial orbits of spinning test particles in rotating boson stars

WebBoson stars are often described as macroscopic Bose-Einstein condensates. By accommodating large numbers of bosons in the same quantum state, they materialize macroscopically the intangible probability density cloud of a single particle in the quantum world. We take this interpretation of boson stars one step further. WebSep 11, 2024 · Abstract. In this paper, we study circular orbits of spinning test particles in the background of a rotating boson star.
