Astrophysics: How fast can you blink?
Chryssa Kouveliotou1
Abstract
Serendipitous observations have revealed fast optical flaring after the onset of X-ray-burst activity from a source in our Milky Way galaxy. It could be the first time this has been observed in a rare kind of neutron star.
Magnetars are slowly rotating neutron stars with extremely strong magnetic fields. Originally classified as members of two distinct families of astronomical objects, soft 
-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs), they were merged into a single class when it was recognized that they share several properties.
