If a star is very hot, the electrons will be freed from the hydrogen atom. (Ionized)

If a star is very hot, the electrons will be freed from the hydrogen atom. (Ionized) Once they are free, they act like particles and emit a continuous spectrum. If the star is hot enough that hydrogen is ionized all the way to the surface, then there will be no hydrogen Balmer lines.
