magnetar
- Magnetars are neutron stars with the strongest magnetic fields known in nature or the laboratory.
- magnetar flare
- giant magnetar
This one was coming from a known magnetar in our own Galaxy, the Milky Way.
- This one was coming from a known magnetar in our own Galaxy, the Milky Way.
- It could fit a slowly rotating neutron star known as a magnetar, which sometimes shows such pauses, but those usually emit much more X-rays.
- So this result kind of confirms the idea that maybe fast radio bursts are being produced by these very chaotic and unpredictable magnetars.
Examples
-
Astronomers detected a powerful burst of X-rays coming from a distant magnetar located in a nearby galaxy.
-
This one was coming from a known magnetar in our own Galaxy, the Milky Way.
-
So, in principle, a magnetar could afford several hundred giant flares in a lifetime.
Academic text (2006) -
The magnetar's internal field is presumed to be even stronger than the external dipole field.
Academic text (2006) -
But as the magnetar cools with age, says the theory, the diffusion of flux lines through the interior and crust slows.

-
A problematic subclass of gamma-ray busters may turn out to be extragalactic magnetars in disguise.
Academic text (2006) -
Long GRBs are intrinsically much more luminous than giant magnetar flares, which put out 10^45 - 10^47 ergs in a fraction of a second.
Academic text (2006) -
So it's clear that SGR bursts and giant flares characterize the same class of relatively nearby objects—presumably magnetars—in different phases of activity.
Academic text (2006) -
The study revealed that the magnetar emitted gamma rays at an intensity never before recorded.

Etymology
Magnetar The word magnetar is built from magnet, meaning 'a thing that attracts metal', and an ending that names a kind of star, so it literally means a 'magnetic star'. So, a magnetar is a type of neutron star with an extremely strong magnetic field that can send out sudden bursts of X-rays and gamma rays.
