Normalized velocities #cod#x2013; v 0 g#cod#x03BB; 12 with normalized time t g#cod#x03BB; 12 for different initial radius r 0 #cod#x03BB; #cod#x003D; 1 the solid line, r 0 #cod#x03BB; #cod#x003D; 2 the dashed line, r 0 #cod#x03BB; #cod#x003D; 3 the dotted line, and r 0 #cod#x03BB; #cod#x003D; 4 the dot-dashed line. The initial perturbation amplitude is fixed as #cod#x003B5; #cod#x03BB; #cod#x003D; 0.001.
