Yo Dawg star? That sounds Sirius.

So, like how a black hole eats a paired star, but with neutronium instead of a singularity.

Hmm... so if this is a supergiant star that's eaten its neutron star companion, wouldn't that increase in mass concentration be enough to overcome the limit of neutron pressure and collapse the whole thing into a black hole?

Could we be witnessing the process of a new type of black hole forming?

The wikipedia article on TZOs says the following (but with a [citation needed] note):

Once the neutron star enters the red giant, drag between the neutron star and the outer, diffuse layers of the red giant causes the binary star system's orbit to decay, and the neutron star and core of the red giant spiral inward toward one another. Depending on their initial separation, this process may take hundreds of years. When the two finally collide, the neutron star and red giant core will merge. If their combined mass exceeds the Tolman-Oppenheimer-Volkoff limit then the two will collapse into a black hole, resulting in a supernova that disperses the outer layers of the star. Otherwise, the two will coalesce into a single neutron star

Now, the team of astronomers have narrowed the selection down to a single red supergiant star in the Small Magellanic Cloud (called HV 2112) that has very similar chemical abundances and temperature to the Thorne-Żytkow model.

And it looks like
