3D velocity analysis of wide binaries supports modified gravity ... - MSN

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 ...
A linear algebraic formulation of discretized, mono-energetic, steady-state, linear Boltzmann transport equations in slab geometry is presented. The discretization consists of a discrete ordinates ...
