Oscillating soliton stars
Abstract
We study a new type of self-gravitating object, described by a soliton solution to the coupled system of the Einstein equation and a matter field equation. The solution describing the self-gravitating object is not static but, instead, is periodic, with both the spacetime geometry and the matter field oscillating in time. In particular, we show that a system described by a real scalar field ${\mathit{g}}^{\mathrm{\ensuremath{\mu}}\ensuremath{\nu}}$${\mathrm{\ensuremath{\varphi}}}_{;\mathrm{\ensuremath{\mu}}\ensuremath{\nu}}$-${\mathit{m}}^{2}$\ensuremath{\varphi}=0 admits such a solution, which is stable under perturbations. The existence of such objects could have important implications for astrophysics and cosmology.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
