Figure 8.5. Left: Mass-radius relation for bare strange stars and for strange stars with the normal crust calculated for the MIT Bag Model EOS with msc2 = 200 MeV, as = 0.2, B = 60 MeV fm-3. Right: the vicinity of the minimum-mass configuration with the crust. Extremal (maximum and minimum mass) configurations are indicated by filled circles. Strange stars with the crust have the maximum crustal density of 4.3 x 1011 g cm-3. The dotted segment represents low-mass configurations unstable with respect to small perturbations. The hatched area is prohibited by General Relativity and by the condition vs < c. The dash-and-dot line gives the radius of the (last) marginally stable circular orbit around a strange star.
