  The determination of mass and radius of a single neutron star EXO 0748-676
has been reported recently. Also, the estimate of radius from the measurement
of moment of inertia of pulsar A in double pulsar system PSR J0737-3039 would
be possible in near future. Here we construct models of static and uniformly
rotating neutron stars involving exotic matter and compare our theoretical
calculations with the recent findings from observations to probe dense matter
in neutron stars.
