“That’s within three to four times the galactic radius,” said Dr. Kremes. “At that distance, you wouldn’t expect to have many stars.”
This can help astronomers explain what an LFBOT is. For now, there are some innovative ideas. The most promising is that it is a giant star, about 20 times the mass of our sun, that has experienced it Supernovas failed Black holes also form in their cores. If the star is massive enough, it may collapse into a black hole instead of exploding again as a supernova. This resulted in a powerful jet shooting outwards and being detected as an LFBOT.
“This is a model that I have tended to prefer over the last few years, but I wouldn’t say I’m ready to say definitively that this is the model,” says Dr. Burley.
Finch can pose a problem for this model. “It is very far from the two neighboring galaxies,” said Dr. Kremes. “No massive star can get there,” unless there is an invisible cluster of stars around it.
Another possibility is that the LFBOT is a tidal disturbance event, in which the black hole feeds on material from a companion star, shining brightly in the process. “But this also has a small problem, because you don’t expect massive black holes to exist outside galaxies,” said Dr. Kremes.
