Star escapes ravenous supermassive black hole, leaving behind its stellar partner
73% Informative
ASASSN-22ci is the result of a feeding supermassive black hole located relatively close to Earth at around 408 million light-years away in the heart of the galaxy WISEA J12204545.05 +493304.7 .
It could result from the black hole catching binary stars, allowing one to escape and then devouring the other.
If so, further observation of this event could solve the mystery of repeating TDEs.
The uniformity of the two flares of ASASSN-22ci appears to indicate they result from the black hole repeatedly disrupting the same star.
If the proposed scenario of a single star getting repeatedly disrupted is the correct one, then the team expects a third flare.
The prediction of when the third flare should occur is based on the separation of two flares.
The predictability of the potential third flare is also a boon for studying these powerful and destructive events.
