maybe their “theories” are wrong

Neutron stars are an interesting phenomenon in that they are extremely dense.  And they have recently found one that is so bright that they can’t explain it with current theories.  This article gives some background into the findings and history of studying these objects:

Since the 1970s, astronomers have been detecting these bright signatures, which they call ultra-luminous x-ray (ULX) sources. Although, the origin of ULXs is still unknown, scientists suspect they could come from this type of binary system between a star and black hole.

About 12 million light years from Earth is the nearby galaxy M82. Toward M82’s center is a binary system between a star and what experts call a rotating neutron star, or pulsar. And when the international team observed this pulsar with NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), they found that it was emitting pulses of x-rays that were brighter than any other pulsar in the known universe.

Let’s find out more on how this is possible on page 2
