The mass, in solar masses, past which neutron stars become rare in Elite Dangerous.

A figure from the game's own generated galaxy rather than from astronomy, and not a ceiling: the game does produce neutron stars above it. It is where the observed population drops off sharply, so a star past it is unusual even by the game's standards.
