the existence of circumstellar disks around sun–like stars was in doubt, with most researchers preferring the hypoth-esis that young stellar objects were surrounded by spher-ical shells of material unlike the solar nebula thought to give rise to the solar system (Rydgren et al., 1978). By the time of Protostars and Planets II, experts in the
Feb 18, 2015· For one thing, the Beta Pictoris disk is exceptionally dusty. This may be due to recent major collisions among unseen planet and asteroid-sized objects embedded within the disk. In particular, a bright lobe of dust and gas on the southwestern side of the disk may be the result of the pulverization of a Mars-sized object in a giant collision.
