Observable effects of a scalar gravitational field in a binary pulsar
Abstract
It is remarked that the Dicke-Brans-Jordan theory of gravitation predicts dipole gravitational radiation from certain binary systems that contain a neutron star or black hole, causing decay of the orbit. Further, it predicts that the true rate of a pulsar clock should vary with distance from a binary companion (other than a black hole). At least one of these effects would be observable in PSR 1913+16.

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.
