[7] In 2012 it was discovered that ID8 and HD 23514, both identified as extreme debris disks (EDD), are variable in 24 μm.

The system interpreted to produce amorphous sub-micron-sized dust, originating in collisions.

[9] Follow-up observations were carried out with Spitzer IRAC (3.6 and 4.5 μm) and ground-based telescopes in 2012 and 2013.

Periodic variations in the 2013 IRAC light curve was interpreted as dust orbiting at around 0.33 astronomical units (AU).

The 2012 impact event occurred at 0.43 AU and involved two bodies with a size of ≥100 km.

The 2014 impact event occurred at 0.24 AU, with the fragments being dominated by boulders with very little vapor condensates.

As the material orbits the star it will pass trough the collision point and the anticollision line.

The simulations did show that the orientation of the impact can cause the material to be spread more widely at the collision point, reducing the short-term variability.
