Final answer:
Circumstellar disks around young stars provide evidence supporting our solar system formation models, with features like gaps in these disks indicating ongoing planet formation processes similar to those in the early solar system.
Step-by-step explanation:
The circumstellar disks observed around young stars provide strong evidence in support of our models for the formation of the solar system, and the presence of these disks is consistent with how we believe our own solar system formed billions of years ago. These circumstellar disks are commonly found around very young stars and often contain structures, such as gaps, which suggest that planet formation processes are occurring. Observations of these protostellar disks support the notion that they are a natural byproduct of star formation and may go on to form planets, much in the same way as our solar system.
Additionally, the internal structure of these disks, including the gap formations attributed to the gravitational influence of newly formed protoplanets, aligns with theoretical models of planetesimal formation and subsequent planet formation. This confirmation comes from various observations including those from the Hubble Space Telescope of regions like the Orion Nebula, where planetary nurseries similar to our early solar system can be seen. Thus, the answer to the question is: True.
