| Abstract: |
We present a Fermi analysis of the gamma-ray source AGL 2241+4454, which is thought to coincide with the Be binary HD 215227 (= MWC 656). In light of the discovery of HD 215227 as the first Be-black hole binary system, we reanalyzed the AGILE flare and the more than 6.5 years of Fermi data. We place new upper limits on the gamma-ray emission from this source and find that it is not likely to be a true gamma-ray binary as previously speculated. |
