Axis ratios b/ a (top) and c/ a (middle), and triaxiality T (bottom) vs. radius from the center of galaxy g15784 for dark matter particles (solid lines) and halo stars (dot-dashed lines). The dark matter halo is oblate in the inner ~15 kpc, transitioning to triaxial (0.33 < T < 0.66) at larger radii. The stellar halo is nearly oblate within ~50 kpc ( T ~ 0.2) and becomes slightly triaxial beyond this radius.
