Why don’t we see hydrogen Balmer lines in the spectra of stars with temperatures of 45,000 K? a. There is no hydrogen in stars this hot. b. The stars are hot enough that most of the hydrogen is ionized and the atoms cannot absorb energy. c. These stars are so cool that nearly all of the electrons in the hydrogen atom are in the ground state. d. Stars of this temperature are too cool to produce an absorption spectrum. e. Stars of this temperature are too hot to produce an absorption spectrum.
