As many as one-third of all short gamma-ray bursts that we observe may come from merging neutron stars in globular clusters. |
There's a big bookkeeping problem here. |
We see these precursor systems, containing one neutron star in the form of a millisecond pulsar, all over the place in globular clusters. Plus, globular clusters are so closely packed that you have a lot of interactions. It's a natural way to make double neutron-star systems. |
