Webb2 Observations of protoplanetary discs The rst protoplanetary discs were observed in the 1980s, and since then we have amassed a huge body of research into their structure and evolution. The subject of protoplanetary disc observations is large enough to form an entire lecture course by itself, so here we merely summarise the most relevant points. 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. fob boris afghanistanWebbIn the previous section, we discussed the formation of a star via the collapse of a big cloud of gas.It is worth noticing that the eight planets in our solar system make up two … green yellow red green format writing
