Internal kinematics of <i>GAIA</i> DR3 wide binaries: anomalous behaviour in the low acceleration regime

The {\it Gaia} eDR3 catalogue has recently been used to study statistically the internal kinematics of wide binary populations using relative velocities two component stars, $\Delta V$, total masses, $m_{B}$, and separations, $s$. For $s \gtrsim 0.01$ pc, these binaries probe low acceleration $a \lesssim 2a_{0}$ regime where gravitational anomalies usually attributed dark matter are observed in flat rotation curves spiral galaxies, $a_{0}\approx 1.2\times 10^{-10}$m s$^{-2}$ is scale MOND. Such experiments test degree generality anomalies, by exploring same independent astronomical systems vastly smaller mass size. A signal above Newtonian expectations when 2a_{0}$, alternatively interpreted as evidence a modification gravity, or due kinematic contaminants; undetected stellar components, unbound encounters spurious projection effects. Here I take advantage enhanced DR3 perform more rigorous than what previously possible. Internally determined masses estimates probabilities for each star spectroscopic information, together with larger sample radial velocities, allow significant improvement analysis careful exclusion possible contaminants. Resulting V$ scalings accurately tracing high regime, but markedly inconsistent one, obtained. non-Newtonian phenomenology thus confirmed.
