We derive an equation of state (EOS) for strange matter, starting from an interquark potential which (i) has asymptotic freedom built into it, (ii) shows confinement at zero density (rho(B)=0) and deconfinement at high rho(B), and (iii) gives a stable configuration for chargeless, beta-stable quark matter. This EOS is then used to calculate the structure of Strange Stars, and in particular their mass-radius relation. Our present results confirm and reinforce the recent claim [1,2] that the compact objects associated with the X-ray pulsar Her X-1, and with the X-ray burster 4U 1820-30 are strange stars.
