A Quality Framework for Testing Gravity with Wide Binaries: No Evidence for MOND
Stephen A. Cookson, Indranil Banik, Kareem El-Badry +4
Wide binaries (WBs) offer a unique opportunity to test gravity in the low-acceleration regime, where modifications such as Milgromian dynamics (MOND) predict measurable deviations…
Wide Binaries from Gaia DR3 : testing GR vs MOND with realistic triple modelling
Charalambos Pittordis, Will Sutherland, Paul Shepherd
We provide an updated test for modifications of gravity from a sample of wide-binary stars from Gaia DR3, and their sky-projected relative velocities. Here we extend on our earlier…
Strong constraints on the gravitational law from DR3 wide binaries
Indranil Banik, Charalambos Pittordis, Will Sutherland +4
We test Milgromian dynamics (MOND) using wide binary stars (WBs) with separations of kAU. Locally, the WB orbital velocity in MOND should exceed the Newtonian prediction by…
Wide Binaries as a Modified Gravity test: prospects for detecting triple-system contamination
Dhruv Manchanda, Will Sutherland, Charalambos Pittordis
Recent studies have shown that velocity differences of very wide binary stars, measured to high precision with GAIA, can provide an interesting test for modified-gravity theories w…
Wide Binaries from GAIA EDR3: preference for GR over MOND ?
Charalambos Pittordis, Will Sutherland
Several recent studies have shown that velocity differences of very wide binary stars, measured to high precision with GAIA, can potentially provide an interesting test for modifie…
Detailed numerical implementation of the wide binary test
Indranil Banik, Charalambos Pittordis, Will Sutherland
The observed flat rotation curves of galaxies are among a number of astrophysical phenomena which require a larger acceleration than can be provided by the Newtonian gravity of the…
Testing Modified Gravity with Wide Binaries in GAIA DR2
Charalambos Pittordis, Will Sutherland
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…
Testing Modified Gravity Theories via Wide Binaries and GAIA
Charalambos Pittordis, Will Sutherland
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…
