Hi. While going through the change.log in 1.4.0pre9, I saw this sentence:

Fixed black holes: infinite radius bug gone, rendered just as a plain black sphere

Does this mean that there is now a spectral class designation for black holes? If so, what class is it? Does the stars.dat database include any black holes?

Black holes have been available for some time, but before the 1.4.0 series there was the problem that the radius was infinite (because you had to supply a finite absolute magnitude, which for an object with zero luminosity resulted in an infinite radius), which limited their usefulness somewhat.

The spectral type code is X.

There are no black holes in stars.dat.
