See here, for example https://www.slac.stanford.edu/econf/C010815/docs/heiselberg.pdf Did you try searching something like "neutron star mass vs radius" on a search engine?

Yeah and all that came up was people looking for EOS's

Did you look at page two of the document I linked? Do you think the EOS matters here?

I meant EOS's were all that came up when I googled my question. This paper clearly has what I wanted. Thank you for linking it. Now all that's left is for me to figure out what all the acronyms are saying.

Is there a mass-vs-radius chart for neutron stars?
