Singularity free stars in \((2+1)\) dimensions. (English) Zbl 1267.83079

Int. J. Theor. Phys. 52, No. 3, 932-945 (2013).
Summary: We present some new types of non-singular model for anisotropic stars with constant \(\Lambda\) and variable \(\Lambda\) based on the Krori and Barua (KB) metric in \((2+1)\) dimensions. The solutions obtained here satisfy all the regularity conditions and its simple analytical form helps us to study the various physical properties of the configuration.
