(Phys.org)—Astrophysicists Adrian Melott and Brian Thomas of the University of Kansas and Washburn University respectively, have published a "brief communication arising" piece in the journal Nature suggesting that the conclusions of a team of Japanese researchers from Nagoya University regarding the source of a carbon-14 bump in AD 774-775 were in error. The Japanese team published an article earlier this year, also in Nature in which they suggested the brief bump in carbon-14 as evidenced by tree samples, was likely not the result of solar flares or a supernova.
