Some fast radio bursts might be the result of a black hole lighting up a neutron star.
Extreme transient events are pushing the limits of our standard explosion models, but magnetars may save the day.
What kind of star is orbiting around a millisecond pulsar and where did it come from?
The authors of this article observe a sudden slowing in the rotation rate of a known magnetar. Although hundreds of glitches (a sudden increase in rotation rate) have been observed in radio pulsars and magnetars, this is the first direct evidence for an anti-glitch.
We’ve detected planets around pulsars before, but this pulsar has an even stranger signal. Could it be due to an asteroid belt similar to the one in our solar system orbiting it?
