New theoretical study of potassium perturbed by He and a comparison to laboratory spectra
N. F. Allard, J. F. Kielkopf, K. Myneni +1
We report on our new calculations of unified line profiles of K perturbed by He using ab initio potential data for the conditions prevailing in cool substellar brown dwarfs and hot…

Temperature and density dependence of line profiles of sodium perturbed by helium
N. F. Allard, K. Myneni, J. N. Blakely +1
Ultracool stellar atmospheres show absorption by alkali resonance lines severely broadened by collisions with neutral perturbers. In the coolest and densest atmospheres, such as th…
