The source is found at a separation of 0 ${_{.}^{\prime\prime}}$ 319 (∼37 au) from the star. Three lines of evidence argue in favour of the signal tracing a protoplanet: (i) it is found …
Webb6 aug. 2024 · Planets form as the dust grains in a protoplanetary disk grow into pebbles and then finally into planets. Because small dust grains interact with gas (via the drag it imparts), the gas in protoplanetary disks influences the distribution of small grains and hence the growth of planets. WebbProtoplanetary disks are the sites of planet formation, and the evolution and eventual dispersal of these disks strongly influences the formation of planetary systems. Disk …

Although shaped like a plate, these disks can be very thick (thicker than the radius of a planet). Gas and dust eventually coalesce to form planets, which then move through the disk collecting more and more material. greater reedville associationA protoplanetary disk is a rotating circumstellar disc of dense gas and dust surrounding a young newly formed star, a T Tauri star, or Herbig Ae/Be star.
