ALMA dusty annular structures: significant implications for planet and star formation theories
Abstract
ALMA uncovered ubiquitous annular gaps and rings in dusty protoplanetary discs with stellar ages in the range from ~0.5 to ~10 Myr, possibly indicating the presence of planets with masses typically in the range from Neptune to Jupiter (Fig. 1). These observations is a quantum leap. For the first time we have planets in live discs, and this constrains both planet formation and protoplanetary disc evolution in novel ways.
