Analytical model of low-mass strange stars using Tolman space–time in \((2+1)\) dimensions
It is hard to explain low-mass strange stars. In this paper, we have modelled these low-mass strange stars using the Tolman IV metric in (\(2+1\)) dimensions. We found that the presence of attractive or positive anisotropic force is the cause for the lower mass of the strange stars in our model. We have also found that the cosmological constant has a significant role in the mass–radius relationship of the stars. We have used our model to predict the radius of a few low-mass strange stars. Our approach is helpful for predicting the crucial parameters of the low-mass strange stars.
