Figure 4: The compactness of a stable boson star (black solid line) as a function of the adimensional
self-interaction parameter . The compactness is shown for the most massive stable
star (the most compact BS is unstable). This compactness asymptotes for to the value
indicated by the red, dashed line. Also shown for comparison is the compactness of a Schwarzschild
BH (green dot-dashed line), and the maximum compactness of a non-spinning neutron star (blue
dotted line). Reprinted with permission from [8]; copyright by IOP.
