They suggested that
the magnetar formed through the interactions of two very massive stars orbiting one another in a binary system so compact that it would fit within the orbit of the Earth around the Sun.

Two common models for gamma - ray emission from FRBs exist: one invoking magnetic flare events from
magnetars — highly magnetized neutron stars that are the dense remnants of collapsed stars — and another invoking the catastrophic merger of two neutron stars, colliding to
form a black hole.
This discovery allowed the astronomers to reconstruct the stellar life story that permitted the
magnetar to
form, in place of the expected black hole [3].
They hunted for runaway stars — objects escaping the cluster at high velocities — that might have been kicked out of orbit by the supernova explosion that
formed the
magnetar.
And, according to Laura Spitler, namesake of the Spitler burst and a researcher at the Max Planck Institute for Radio Astronomy, in Bonn, Germany,
magnetars generally
form from stellar explosions called Type - I superluminous supernovas.
