https://iopscience.iop.org/article/10.1086/321734/pdf My question given this report. We should see geologic time scale periodic dust clouds (or cycles) passing through our system. The report shows a narrowing of debris relative to sol though still passing approximately around Sirius now. These reports are not clear on how much debris and when they will pass sol.
Also note the new dust in our system is originating on top of our solar system which matches the angle the dust should come in from the dwarf galaxy.
