  There are three categories of stars whose masses have been found accurately
in recent times: (1) two for which Shapiro delay is used which is possible due
to GR light bending as the partner is heavy : PSR J1614-2230 and PSR J1903+0327
(2) six eclipsing stars for which numerical Roche Lobe geometry is used and (3)
3 stars for which spectroscopic methods are used and in fact for these three
the mass and radii both are estimated. Motivated by large color (N_c) expansion
using a modified Richardson potential, along with density dependent quark
masses thereby allowing chiral symmetry restoration, we get compact strange
stars fitting all the observed masses.
