Deletion of Daemon (astrophysics)

Comment: Do either of those sources even count as reliable sources in any event?  At best, they're |primary sources, and at worse are less than that.  I'm not wholly familiar with astrophysics publishing practices, but I thought that "Letters" articles in most fields aren't considered to be fully peer-reviewed.  The other source is to an Invited Talk, which again, often doesn't rise to the full level of peer review we'd like for a Wikipedia science source.  To me this looks like a non-notable scientific idea that could possibly be covered in brief in another article, if at all
