Abstract
Type Ibn supernova SN 2010al is explored to infer parameters of supernova and a circumstellar (CS) shell. The CS interaction model combined with the spectral model of 4600 Å blend suggests the explosion of a WR star with the energy of \((1{-}1.5)\times 10^{51}\) erg inside a dense confined CS shell with the mass of \({\sim}0.1M_{\odot}\) and kinetic energy of \({\sim}10^{48}\) erg. The confined CS shell has been formed during the last 0.4 yr prior to the core collapse.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
