Query: Singularity free anisotropic strange quintessence star   Present paper provides a new model of anisotropic strange star corresponding
to the exterior schwarzschild metric. The Einstein field equations have been
solved by utilizing the Krori Barua (KB) ansatz in presence of quintessence
field characterized by a parameter omegaq . The obtained solutions are free
from central singularity. Our model is potentially stable.The numerical values
of mass of the different strange stars SAXJ1808.4-3658(SS1)(radius=7.07
km),4U1820- 30 (radius=10 km),Vela X-12 (radius=9.99 km),PSR J 1614-2230
(radius=10.3 km) obtained from our model is very close to the observational
data that confirms the validity of our proposed model. The interior solution is
also matched to the exterior Schwarzschild spacetime in presence of thin shell
where negative surface pressure is required to hold the thin shell against
collapse.
