The Chemical Composition of Alpha Centauri A: Strong Lines and the ABO Theory of Collisional Line Broadening
Marianne T. Doyle, B. J. O'Mara, J. E. Ross +1
The mean abundances of Mg, Si, Ca, Ti, Cr and Fe based on both strong and weak lines of Alpha Centauri A are determined by matching the observed line profiles with those synthesize…

Semi-classical theory of collisional depolarization of spectral lines by atomic hydrogen. I: application to p states of neutral atoms
M. Derouich, S. Sahal-Brechot, P. S. Barklem +1
The present paper extends the method of Anstee, Barklem and O'Mara (Anstee 1992; Anstee & O'Mara 1991, 1995; Anstee, O'Mara & Ross 1997; Barklem 1998; Barklem & O'Mara 1997; Barkle…

Self-broadening in Balmer line wing formation in stellar atmospheres
P. S. Barklem, N. Piskunov, B. J. O'Mara
Details of a theory of self-broadening of hydrogen lines are presented. The main features of the new theory are that the dispersive-inductive components of the interaction (van der…
