15-75 and 12-80 are close enough for me! Carroll and Ostlie (2nd ed) suggest 13 and 72 Jupiter masses, so I think we're in the ballpark. They also extend the familiar OBAFGKM sequence with spectral types L and T, both of which are described as brown dwarf spectra.

Generally, stars that are >150 solar masses generate so much energy that they blow themselves up, but R136a1, in the LMC, is 265 solar masses, with a birth weight of 320 solar masses. Does anyone have an explanation? At the moment, I think R136a1 is a blue straggler, but I'm unsure.

I'm doing a research project on brown dwarfs. Does anyone know anything more about them? If so, also include a bibliography, thank you very much.
And there's the theoretical Y spectral class for extremely cool brown dwarfs.
