WebDec 13, 2024 · To confirm the flare star hypothesis, on 2024 November 23.27 UT we obtained a spectrum of J004123.75+411459.6 with the LRS2 spectrograph on the Hobby–Eberly Telescope (HET). ... The spectrum, shown in Figure 1, is that of a classic dMe flare star. The strength of the TiO bandheads at ∼5430 Å and ∼6150 Å suggest a … 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.
