Ultraviolet radiation physics in astronomy and geophysics
Journal of Quantitative Spectroscopy and Radiative Transfer, 1962Abstract The astrophysicist has been compelled, in his studies of the solar and stellar atmospheres, to abandon in some cases the simpler “local thermodynamic equilibrium” approach. The new approach assumes statistical equilibrium and writes equations which concern the transfer of energy.

A Discussion on astronomy in the ultraviolet - The ultraviolet spectrum of B-type supergiants
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1975Abstract The broad, steep-sided absorption lines in B-type supergiant spectra are stronger than the absorption lines in main-sequence stars. In addition to lines from the second, third and fourth spectra of the light elements and the metals there is a broad, pointed feature at 1720 A which has constant strength in the B-type ...
