Q&A: Supernova Remnants and Neutron Stars
Does Chandra register something about the Magnetars?
Magnetars are a name given to some neutron stars that may have very
magnetic fields, about 100 trillion times as strong as the Earth's
field. These fields are postulated to explain some of the properties of
groups of neutron stars called "soft gamma-ray repeaters" -- because
repeated gamma ray bursts unlike the strong gamma-ray bursts, and
X-ray pulsars" -- because they seem to be rotating too slowly to produce
observed energy output. Other explanations are possible, so this
hypothesis is still controversial. Anyway, Chandra has observed a half
or so of these objects (see list, below), but the mystery still remains.
