Collision-induced satellite in the blue wing of the Balmer-beta line and consequences on the Balmer series
F. Spiegelman, N. F. Allard, J. F. Kielkopf
In this paper we emphasize the non-Lorentzian behavior of the Balmer series in helium-dominated DBA white dwarf stars for which the decades-old problem exists for the determination…

Collisional effects in the blue wing of the Balmer-alpha line
N. F. Allard, F. Spiegelman, J. F. Kielkopf +1
In order to investigate the near wing of the Lyman-alpha line, accurate line profile calculations and molecular data are both required due to the existence of a close line satellit…

Collisional effects in the blue wing of Lyman-alpha
F. Spiegelman, N. F. Allard, J. F. Kielkopf
Spectral observations below Lyman-alpha are now obtained with the Cosmic Origin Spectrograph (COS) on the Hubble Space Telescope (HST). It is therefore necessary to provide an accu…
