about this clustering, what's the average distance between the stars in lightyears? so the suggestion is that because these stars have similar as of yet unexplained features and are clustered together that these features could be artificial?

The author is careful not to suggest that in the paper, but the implication is that this is a stellar empire with ET's transforming the systems that they are colonizing. The author is also quite clear about the results not being significant and that the cluster is of "questionable reality".

  "somewhat uncertain" is the actual quote. And further "Using this as the probability of randomly drawing a star in the clump area, the bionomial distribution yields a probability of randomly drawing at least 12 stars in the clump out of 15 in the Paper I field of 0.07." That I believe is approx 1 in 20 of seeing the observed distribution. Suggestive.

I would agree that is implied in the call for SETI to target them. The implication is the spread of a civilization to "nearby" stars could be responsible for the observations. Without anything but wild guess to go on much closer transient (natural) obstructions in our line of sight could cause dips in a small region too. I would like to think we have some way to rule this out. Or further fetched, common formation seeded them with "something peculiar" and they are still neighbors. But again much like the GP question of what is the avg dist between what is common about their size age, composition etc, other than they seem to (slowly) dim?

  The likelihood of them behind Neighbors and sharing those characteristics is low. Our stars stellar siblings are no longer clustered.

It could have something to do with theories about how solar systems form. If you find a bunch of systems with similar attributes, in the same neighborhood, maybe it's because they all formed from the same dust cloud. Maybe swirling eddies in the cloud each became a solar system.
