The abstract of this paper says: Consistent with previous research, the flow of articles by collaborators into affected fields decreases precipitously after the death of a star scientist (relative to control fields). In contrast, we find that the flow of articles by non-collaborators increases by 8% on average. I haven't read the paper, and maybe this is just completely wrong, but wouldn't we expect the number of published papers by non-collaborators to rise no matter what? I mean, a star scientist is dead now. There are no more papers coming from that person. Of course other people's papers fill the gap. The number of journals didn't change. The number of articles in an issue of each journal didn't change. These journals need to get articles from someone.
