WebThe results are then applied to problems covering a wide range of masses and radii of the boson stars and the relevant self interaction parameters are calculated. We compare our results with earlier treatments to show the applicability of the geometrical approach. Keywords Exact solution · Einstein-Klein-Gordon equation · Boson star · Dark ... WebMar 2, 2024 · So finding boson stars would go at least some way towards solving one of the biggest mysteries of the cosmos. According to the team's calculations, if GW 190521 was a merger between two boson stars, the masses and distances involved would be different, but it would solve the problem of that 85-solar-mass black hole.

WebMay 8, 2012 · The idea of stable, localized bundles of energy has strong appeal as a model for particles. In the 1950s, John Wheeler envisioned such bundles as smooth configurations of electromagnetic energy that he called geons, but none were found. Instead, particle-like solutions were found in the late 1960s with the addition of a scalar field, and these were … WebLecture 25.
