Modified gravity scenarios where a change of regime appears at acceleration scales a<a0 have been proposed. Since for 1M⊙ systems the acceleration drops below a0 at scales of around 7000 AU, a statistical survey of wide binaries with relative velocities and separations reaching 104 AU and beyond should prove useful to the above debate. We apply the proposed test to the best currently available data. Results show a constant upper limit to the relative velocities in wide binaries which is… Expand

Wide binaries as a critical test for Gravity theories
Assuming Newton's gravity and GR to be valid at all scales leads to the dark matter hypothesis as a requirement demanded by the observed dynamics and measured baryonic content at galactic andExpand
A Phase Space Diagram for Gravity
Surprisingly, extrapolation to atomic scales suggests gravity should be at the dark matter mimicking regime there, in addition to the one introduced by the criterion v < c of the Schwarzschild radius, rS = 2GM/c2. Expand
Modified Newtonian Gravity, Wide Binaries and the Tully-Fisher Relation
A recent study of a sample of wide binary star systems from the Hipparcos and Gaia catalogues has found clear evidence of a gravitational anomaly of the same kind as that appearing in galaxies andExpand
Dynamics of wide binary stars: A case study for testing Newtonian dynamics in the low acceleration regime
Extremely wide binary stars represent ideal systems to probe Newtonian dynamics in the low acceleration regimes ( 0.15 pc that are useful for the proposed test. While it would be premature to drawExpand
Gravitational Anomalies Signaling the Breakdown of Classical Gravity
Recent observations for three types of astrophysical systems severely challenge the GR plus dark matter scenario, showing a phenomenology which is what modified gravity theories predict. StellarExpand
Challenging a Newtonian prediction through Gaia wide binaries
Under Newtonian dynamics, the relative motion of the components of a binary star should follow a Keplerian scaling with separation. Once orientation effects and a distribution of ellipticities areExpand
Testing modified gravity with wide binaries in Gaia DR2
Several recent studies have shown that very wide binary stars can potentially provide an interesting test for modified-gravity theories which attempt to emulate dark matter; these systems should beExpand
The geometric challenge of testing gravity with wide binaries
Wide binaries provide promising laboratories for testing general relativity (GR) in the low-acceleration regime. Recent observational studies have found that the difference in the proper motionsExpand
Testing modified-gravity theories via wide binaries and GAIA
The standard LambdaCDM model based on General Relativity (GR) including cold dark matter (CDM) is very successful at fitting cosmological observations, but recent non-detections of candidate darkExpand
Testing Newton/GR, MoND and quantised inertia on wide binaries
Wide binary stars are within the low-acceleration regime in which galactic rotation curves deviate from Newtonian or general relativistic predictions. It has recently been observed that theirExpand

A test using gas rich galaxies for which both axes of the BTFR can be measured independently of the theories being tested and without the systematic uncertainty in stellar mass that affects the same test with star dominated spirals is reported. Expand
A natural approach to extended Newtonian gravity: tests and predictions across astrophysical scales
In the pursuit of a general formulation for a modified gravitational theory at the non-relativistic level and as an alternative to the dark matter hypothesis, we construct a model valid over a wideExpand
Modified Newtonian dynamics as an alternative to dark matter
▪ Abstract Modified Newtonian dynamics (MOND) is an empirically motivated modification of Newtonian gravity or inertia suggested by Milgrom as an alternative to cosmic dark matter. The basic idea isExpand
The evolution of wide binary stars
We study the orbital evolution of wide binary stars in the solar neighbourhood due to gravitational perturbations from passing stars. We include the effects of the Galactic tidal field and continueExpand

Large scale structure in Bekenstein's theory of relativistic modified Newtonian dynamics.
It is shown that it may be possible to reproduce observations of the cosmic microwave background and galaxy distributions with Bekenstein's theory of MOND, and the evolution of the scalar field is akin to that of tracker quintessence fields. Expand
An $\mathsf{f(R)}$ gravitation for galactic environments
We propose an action-based $ f(R) $ modification of Einstein's gravity that admits a modified Schwarzschild-deSitter metric. In the weak field limit this amounts to adding a small logarithmicExpand

We investigate the possibility that the observed flatness of the rotation curves of spiral galaxies is not evidence for the existence of dark matter haloes, but rather a signal of the breakdown ofExpand
