WebUsing linear analyses and numerical simulations, it addresses how a disk evolves through the development of instabilities, and also presents a new instability driven by dust coagulation. As a result, the simulation demonstrates a scenario of planetesimal A successive development of multiple instabilities triggers planetesimal formation in ... WebDefinition. A protoplanetary disk is a disk of gas (99% by mass) and dust (1%), orbiting a newly formed star, from which planets are (hypothesized to be) formed. Disks are common by-products of star formation, and range in mass from 0.001 to 0.3 Solar masses (10 27 –10 29 kg) and in size from several tens to almost 1,000 Astronomical Units ...

WebWe propose therefore that the planetesimal belts in debris disks are the result of dust traps in structured disks, whereas protoplanetary disks without dust traps decrease in dust mass through radial drift and are therefore undetectable as debris disks after the gas dissipation. These results provide a hypothesis for a novel view of disk evolution. Webtransitional disks, but also the degree of grain growth in the transitional disks. I expect that this study will help to enhance our understanding on planet formation. 2-2. Environmental …
