Correct, it only works with AA. Still, though, only to an extent and some still
disappear entirely.
If a star is "between the cracks" AA will completely miss it, because neighboring
pixels will be black. In the case
of getting caught and aa'd, the aa will of course decrease brightness as the star is
only part of the pixel.
Angular size is still the predominant factor.
It is very annoying to create good stars in POV when changing quality settings from
one render to another!
