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. Authors: Mullan, D J [1] WebJan 8, 2024 · Some stars, especially red dwarfs, can flare frequently and violently. A team of researchers studied how flaring activity affects the atmosphere and potential for life on …

WebObservations at three epochs from 2012 to 2024 span nearly a full activity cycle, sample two rotations of the star and two orbital periods of the planet, and reveal a multitude of brief flares. From 2012 to 2024, the star's 7.75 ± 0.10 yr activity cycle produced the largest observed variations, 38% ± 3% in the summed flux of the major FUV ... WebA possible interpretation is that the flare originates from the merger product recoiling at high velocity through a dense gas accretion disk as its Hill sphere ablates via ram-pressure. This would be the first black hole binary merger found to have an electromagnetic counterpart.
