Pressure Shifts of Metal Lines in Cool White Dwarfs
1989
International Astronomical Union Colloquium
Preserved Fulltext
AbstractModel atmosphere techniques and an experimentally confirmed theory of collision broadening of CaII H and K by helium have been combined to shou that the difference in velocity shifts for the two lines is a sensitive diagnostic for the H/He abundance ratio in cool, metallic line uhite dwarfs.
