'Eleven years after the publication of its first edition, Armitage revisits this graduate-level textbook on the astrophysics of planet formation to update it based on the trove of knowledge produced by the Kepler space telescope and ALMA that revolutionized our concept of what planetary systems look like. The book covers the structure and evolution of protoplanetary disks and the formation of planetesimals within them, the formation of rocky and giant planets, as well as the evolution of protoplanetary systems. The astrophysics is put into context by an introductory chapter on what observations are currently telling us.' Karouzos Marios, Nature Astronomy
