Wide binaries without viable bound Newtonian orbits
L. Pasquini, R. Saglia, F. Patat +7
Context. Wide binaries offer a unique opportunity to test gravity in the low acceleration regime, where deviations from Newtonian dynamics may appear. Aims. We use high-resolution…

Testing gravity with wide binaries -- 3D velocities and distances of wide binaries from Gaia and HARPS
R. Saglia, L. Pasquini, F. Patat +5
Wide Binaries (WBs) are interesting systems to test Newton-Einstein gravity in low potentials. The basic concept is to verify whether the difference in velocity between the WB comp…
