We have no explanations for this sort of slow repeat.

Probably a solar garden light that got flung into space and is rotating.
GPM J1839–10 takes 22 minutes between pulses.
End Times starts playing
The article makes no mention of the possibility of this being a binary system of some sort, although I would guess the physics involved for this type of burst are equally lacking in current models.
Because that doesn’t fit.
The object sends X-ray pulses for 30-300 seconds every 22 minutes.
For a binary star system we would expect to see pulses while the neutron star is not behind the star and a short period without any pulses while the other star blocks it. Which is the inverse of the recorded pattern
In a tertiary or greater star system you could have longer periods where the star is blocked but the time between pulses would vary depending on the positions of other stars.
Personally I think it will end up being a pulsar that is slowing down and becoming a regular neutron star with something externally adding/removing mass from it causing it to speed up again.
