WebNov 19, 2024 · The star, known as KIC9944137, lies more than 1800 light-years away between the constellations Cygnus and Lyra. It closely resembles our Sun: about the same size, about the same temperature, about the same rotation rate. Yet the flare was at least 10 times as powerful as anything recorded on the Sun. WebSep 1, 2009 · However, based on the properties of the flares, and based on a recent model of rotating magnetospheres, we argue that, rather than attributing the two flares to a late-type dwarf, it is a viable hypothesis that the flares were magnetic phenomena associated with the rotating magnetosphere of the B2p star itself.
