Query: Analytical model of low mass strange stars in 2+1 spacetime   The low mass compact stars are quite fascinating objects to study for their
enigmatic behaviour. In this paper, we have modeled this kind of low mass
strange stars based on the Heintzmann ansatz (H. Heintzmann., Zeitschrift f\"ur
Physik, vol.228, 489, 1969.) in $(2+1)$ dimension. Attractive anisotropic force
plays a significant role to restrict the upper mass limit (which is
comparatively low) of the strange star. We have applied our model to some low
mass strange stars. Our model could be useful to predict the important
parameters of the low mass strange stars.
