Planetary embryo collisions and the wiggly nature of extreme debris discs

In this paper, we present results from a multi-stage numerical campaign to begin explain and determine why extreme debris disk detections are rare, what types of impacts will result in disks can learn about the parameters collision disks. We by simulating many giant using smoothed particle hydrodynamical code with tabulated equations state track escaping vapour collision. Using an $N$-body code, simulate spatial evolution generated dust post-impact. show that release anisotropically not isotropically as has been assumed previously distribution resulting is dependent on mass ratio impact angle addition, anisotropic post-collision cause formation or lack short-term variation flux depending orientation respect orbit around central star. Finally, our suggest there narrow region semi-major axis where would be observable for any significant amount time implying most observed often but does mean collisions occurring.
