Abstract

WHILE the general behaviour of the absorption lines in stellar spectra has been well accounted for by thermodynamic theory, the Balmer series shows marked peculiarities. In spite of the very high resonance potential, these lines appear even in stars of class G, and their intensity is conspicuously affected by absolute magnitude—that is, by the density of the stellar atmosphere.
