Shaking Up Debris Disks
Using a combination of numerical and analytic techniques, the authors of this paper try to answer the question: what does a passing star do to a debris disk?
Could We Observe Aliens Mining Asteroids?
The authors consider a possible signature of an intelligent, spacefaring life form, more technologically advanced than ourselves: they consider the effects that significant asteroid mining would have on a debris disk and determine whether these effects would be observable.
