Compact objects in entangled relativity

We describe the first numerical Tolman-Oppenheimer-Volkoff solutions of compact objects in entangled relativity, which is an alternative to the framework of general relativity that does not have any additional free parameter. Assuming a simple polytropic equation of state and the conservation of the rest-mass density, we notably show that, for any given density, compact objects are always heavier (up to similar to 8%) in entangled relativity than in general relativity-for any given central density within the usual range of neutron stars' central densities, or for a given radius of the resulting compact object.

Automated summary

In entangled relativity, compact objects are always heavier than in general relativity for any given density.
