Could two rotating binary neutron stars create massive cosmic rays if their magnetic fields overlapped and acted on a volume of gas?
The so-called GZK cosmic rays sometimes have an energy equivalent to a baseball moving at 30 m/s.
The source of these rays has yet to be determined. Could 2 rotating neutron stars orbiting one ...

Meaning of Left-Right Arrow in a Fitting Formula [duplicate]
I initially posted this question on Astronomy Stack Exchange but the site seemed rather inactive so I will try to ask it again on Physics, hopefully it doesn't go against any rules.
I was reading this ...

Approximation concerning gravitational waves from binary neutron star
I'm interested in studying two neutron stars orbiting each other and producing gravitational waves. In textbooks the calculation for the power of the radiation is done by considering the neutron stars ...

How do tidal forces change gravitational waves
If there is a binary of two neutron stars, they are going to be deformed because of the tidal forces. I suppose that it will cause a change in the movement of the stars and that will cause a change in ...

Are there any black hole neutron star binary?
Has a black hole-neutron star binary aver been observed?
I mean observed in any way: gravitationally, through eclipse, or any other means.
EDIT Thanks to the comment to this question, we know that ...

How do neutron star binaries form?
Do neutron star binary systems come from previously active-star binaries, where where both stars have gone supernova and left behind neutron stars that are still in orbit? Or do they form when two ...

What's the shortest "safe" distance from a neutron star merger?
Take GW170817 for example, the first neutron star collision picked up by LIGO. Given how much data we got from that event, can anyone figure out what the "blast radius" is, and how far away from the ...

Gravitational waves and chirp waveform
When two neutron stars collide emitting gravitational waves, what exactly does the chirp waveform represent and how is it used to infer the distance to the source?

Magnetar's magnetic field near a black hole (novice question)
Even light cannot escape the event horizon of a black hole. Now, imagine a magnetar orbits a black hole. The magnetar orbits too far to be ripped and consumed by the black-hole. However, its magnetic ...

Can a binary star system create a stationary black hole?
Research over the last 200 years suggests that half or more of visible stars are part of multiple star systems.
I apologise for the number of assumptions in my question but, because of the numbers of ...

Pulsar-white dwarf binary
In the paper from Hulse & Taylor 1975 on the first discovery of a pulsar in a binary system, they conclude that the companion to the pulsar must be
a compact object, probably a neutron star or ...
