Boson stars and oscillatons in an inflationary universe
Spherically symmetric gravitationally bound, oscillating scalar lumps (boson stars and oscillatons) are considered in Einstein’s gravity coupled to massive scalar fields in 1+D-dimensional de Sitter-type inflationary space-times. We show that due to inflation bosons stars and oscillatons lose mass t...

| description | Spherically symmetric gravitationally bound, oscillating scalar lumps (boson stars and oscillatons) are considered in Einstein’s gravity coupled to massive scalar fields in 1+D-dimensional de Sitter-type inflationary space-times. We show that due to inflation bosons stars and oscillatons lose mass through scalar radiation, but at a rate that is exponentially small when the expansion rate is slow. |
