Several Double Planetary Disks Found
- Recently, astronomers used radio and optical telescopes to study double planetary disks around binary stars, showing differences in their disks whether they formed together or not.
- The collection of material around binary stars, called "protoplanetary disks," formed from raw materials as parent stars.
- DF Tau, situated over 400 light-years away in the constellation Taurus, has peculiar characteristics where its ‘double’ planetary disks show distinct differences and only the primary star has an active inner disk.
- The research around the system suggests that the dispersal of circumstellar disks is complex and there is more to disk evolution than just time.
- Planetary disks are giant wheels spinning in molecular clouds forming planetesimals and ultimately planets.
- Finding planetary disks around other stars gives an insight into the early stages of the formation and evolution process.
- The survey conducted by the astronomers will shed some light on the process of planetary formation in paired disks and help understand their evolution.
- Their data may highlight the individual viscosities of the disks and the presence of a substellar companion carving out gaps around the secondary star to explain the dissipation differences.
- Research surrounding the processes of planetary formation and circumstellar evolution should help understand the realms with respect to planet formation.
- Checking out more binaries should give us a better understanding of binary star and planet evolution.
