The superluminous transient ASASSN-15lh as a tidal disruption event from a Kerr black hole

When a star passes within the tidal radius of a supermassive black hole, it will be torn apart1. For a star with the mass of the Sun (M ⊙) and a non-spinning black hole with a mass 108 M ⊙ 12,13, a star with the same mass as the Sun could be disrupted outside the event horizon if the black hole were...

Zusammenfassung:When a star passes within the tidal radius of a supermassive black hole, it will be torn apart1. For a star with the mass of the Sun (M ⊙) and a non-spinning black hole with a mass 108 M ⊙ 12,13, a star with the same mass as the Sun could be disrupted outside the event horizon if the black hole were spinning rapidly14. The rapid spin and high black hole mass can explain the high luminosity of this event.
