Query: Analytical model on mass limit of strange stars   In this paper, we present a new kind of stellar model using the Nariai IV
metric. This model can be used to study the strange/quark stars(which is our
present interest, though it can also be applicable to neutron stars). We
present a mass-radius region where all the regularity conditions, energy
conditions, the TOV equation, and stability conditions are satisfied. According
to our model, strange stars having mass up to $1.9165M_{\odot}(=2.81 km)$ is
stable. A strange star having a mass greater than $1.9165M_{\odot}$ violates
the stability conditions. This model can be very useful to predict the radius
of strange stars of mass greater than $1 M_{\odot}$.
