Abstract.

The present paper provides a new class of interior solutions which satisfies the Karmakar condition (K.R. Karmarkar, Proc. Indian Acad. Sci. A 27, 56 (1948)). The model is generated by assuming a reasonable choice for the metric potential \( g_{rr}\) and the model parameters are obtained accordingly since, in the case of embedding class-I, the metric co-efficients are dependent on each other. We match our interior solution to the exterior Schwarzschild line element in the presence of thin shell. The proposed model does not suffer from central singularity. The model is discussed for a neutron star of mass \( 1.4 M_{\odot}\) and radius 10km. The potential stability condition of the model is also discussed.
