Apparently the smallest a neutron star could theoretically be is 0.1 - 0.2 Solar masses. [0]

And then 1.4 Solar masses is the upper limit. [1]

The Chandrasekhar limit is the maximum size of a white-dwarf, not a neutron star. It's usually defined as the minimum size of a neutron star (since it has to overcome electron-degeneracy pressure). The TOV limit[0] is the maximum size of a neutron star.

Ah yes - you’re right.

I was thinking of neutron stars all along - which, correct me if I’m wrong, look like they have similar density to an atomic nucleus and for which the upper limit is apparently 3 Sols. [0]

How much bigger can a neutron star be given the TOV limit vs. the Schwarzschild radius winking the whole thing into a black hole?
