Table 2:

Parameters of the bag models for strange stars.
EOS	B	$m_{\rm s} c^2$	$M_{\rm max}^{\rm stat}$	R_1.4
	[ ${\rm MeV~fm^{-3}}$ ]	[ ${\rm MeV}$ ]	[ $M_\odot$ ]	[km]
SQM1	56	200	1.90	11.27
SQM2	45	185	2.02	11.86
SQM3	67	205	1.65	9.94

B - MIT bag constant, $m_{\rm s}$ - strange quark mass. For all models, the QCD coupling constant equals $\alpha_{\rm s}=0.2$ . The maximum allowable mass for non-rotating stars, $M_{\rm max}^{\rm stat}$ , and the circumferential radius of non-rotating stars of $1.4~M_\odot$ , R_1.4, are given in the last two columns, respectively.
