    Default spirals in proto planetary disks caused by shadows



    this is a mix of old and new. Lin and Shu showed that any perturbation of a disk of orbiting Particles will result in spiral shaped density waves. the density waves of galaxies are perturbed by satellites and interlopers. here it is shown that shadow effects can cause spiral density waves in photo planetary disks. quite elegant. an interesting generalization of Lin and Shu's 50 year old result.
