Hyperflare

Such hyperflares may be the result of phase transitions from neutron matter to hyperon or strange-quark matter in hyperstars.

We report an analysis of archival RXTE data from the 2004 December hyperflare from SGR 1806-20.

For hyperflare events occurring at the time of advanced detector operation, the observable GW energetics at 100 Hz would be close to 10⁻³⁶J, leading to stringent constraints on the magnetar model.

This seems very plausible, as statistical and energetic considerations allow one to explain basic properties of FRBs with transformation of a tiny fraction (~10⁻⁵) of the magnetar hyperflare (~10⁻⁴⁴ -10⁻⁴⁶ erg) into a short radio burst.
