Solar Superflares during the Last 15 ka: Myth or Reality?
We discuss 13 known rapid increases in radiocarbon content in the Earth’s atmosphere and all proposed to date hypotheses of their origin. Comparing the occurrence probability of 4 most powerful events, prescribed likely to the solar superflares, with the Kepler’s mission data it results in a significant discrepancy at least assuming flare energy E ∼ 1035 erg. The hypothesis of solar superflares (or sequence of flares) cannot likely be the only one accounting for the origin of all measured 14C signals. For example, some events could be explained by the Solar system encounter with the interstellar inhomogeneities (clouds). For two of them (660 BCE and/or 813 BCE) there is a critical experiment on 3He content increase in Antarctic ice supporting this suggestion. However, none of the proposed hypotheses can reliably satisfy the experimental data.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
