FIG. 3: The surface tension is plotted against radial coordinate while other parameters are fixed at b$_{0}$ = − 1, m = 2 and α = − 3 , 2 , 3 (top to bottom). FIG. 4: The equation of state parameter ω is plotted against radial coordinate while other param- eters are fixed at b$_{0}$ = − 1, m = 2 and α = 1 , 2 , 3 (top to bottom). 9
