If this stuff is true:
- Classical Oort Cloud:
- Mainly composed of objects from the disks of other stars.
- A significant fraction of objects are from the Nice disk.
- Inner Oort cloud:
- Mainly composed of objects from the Jupiter-Saturn region.
- Long-period: Some
- formed in the Uranus-Neptune zone according to the classical theories,
- formed in the Uranus-Neptune zone if scattered disk contributes,
- formed in the Jupiter-Saturn zone if Sedna-population is important,
- formed around other stars according to our new model.
- Unfortunately, it is not clear how we can determine the mixing ratio.
- Part from Oort cloud. ...... These will look like LPCs.
- Part from the scattered disk. ...... These are from the Uranus-Neptune zone.
- I think that more numerical modeling can solve this issue.
