Strong constraints on the gravitational law from $Gaia$ DR3 wide binaries

Indranil Banik, Charalambos Pittordis, Will Sutherland +4

We test Milgromian dynamics (MOND) using wide binary stars (WBs) with separations of $2-30$ kAU. Locally, the WB orbital velocity in MOND should exceed the Newtonian prediction by…
