GravSphere2 extends Jeans modeling to fourth order with LOS and PM data plus flexible anisotropy forms to recover mass density, anisotropy, and density slope in spherical stellar systems while breaking the mass-anisotropy degeneracy.
N-body simulations of ultra-faint dwarf galaxies without dark matter find a 3-billion-year quasi-stationary phase followed by mass segregation, with binaries causing substantial overestimates of velocity dispersion.

GravSphere2: A higher-order Jeans method for mass-modeling spherical stellar systems
GravSphere2 extends Jeans modeling to fourth order with LOS and PM data plus flexible anisotropy forms to recover mass density, anisotropy, and density slope in spherical stellar systems while breaking the mass-anisotropy degeneracy.
