Supernova remnant and ejecta "bullet"

I'm making an X-ray analysis of the source SNR N49. It has a magnetar inside of it that is emitting strongly in Soft ([0.2-1.2] keV), Medium ([1.2-2.5] keV), and Hard ([2.5-8.0] keV) bands. I was ...

Is "magnetars don't last long — just a year to a few years" really true? Is it a misquote or perhaps taken out of context?

NASA's Two Sides of the Same Star discusses the relationship between pulsars and magnetars and contains a video also linked below. At 02:13 it quotes "Tom ...

What would a kHz gravitational wave detector look like? (mountains on millisecond magnetars) How would it differ from LIGO/Virgo?

The abstract of Gravitational waves from mountains in newly born millisecond magnetars says: In this paper we study the spin-evolution and gravitational-wave luminosity of a newly born millisecond ...

Can a pulsar also be a magnetar?

I know this is a simplistic question, but I cannot find a straight answer... Also, is it possible most or all neutron stars are magnetars and/or pulsars? It's just hard to see all of their properties ...

What would you call death by magnetar?

The magnetic field of a magnetar is so strong that it would stretch people's atoms apart. This, would obviously, result in death. But how spaghettification refers to death by extreme tides, and for ...

In practice, can very high magnetic fields significantly alter the dynamics of an astronomical-scale bodies?

The direct effect of magnetic fields on the dynamics (as in the movements, trajectories etc of the bodies themselves, rather than lower-level phenomena like stellar winds and atmospheric degradation) ...
