This article is a little short on information, so far I haven't been able to find anything on the astronomer either.

I cannot find anything on him either. But Pulkovo Observatory is one of major (possibly, the major) Observatories in Russia and he is listed on their stuff page. They list his degree as Dr. Sc. which is the second doctoral degree in Russia, after the regular Ph.D. (which is called Cand. Sc.).

So, he appears to be an established scientist and I am confused why google does not find him. The article might be transcribing his name into English differently from the normal way. That is often a problem with Russian names.

Seconded. Google on "Abdusamatov solar" and you'll find a few references to him (make sure it's "Kh Abdusamatov"). Still not much to go on.
