There are spiral galaxies with numerous, ragged spiral arms in their disks (called ``flocculent'' spirals), so perhaps the self-propagating star formation mechanism is responsible for the flocculent spirals. A ``grand-design''spiral seen face-on. A flocculent spiral with ragged spiral arms.
Logarithmic Spiral. The logarithmic spiral is a spiral whose polar equation is given by. (1). where is the distance from the origin, is the angle from the x-axis, and and are arbitrary constants. The logarithmic spiral is also known as the growth spiral, equiangular spiral, and spira mirabilis.
