Increased Lyα Opacity in White Dwarf Photospheres from Transient H− Resonances

Increased Lyα Opacity in White Dwarf Photospheres from Transient H− Resonances

The structure and emergent flux of hydrogen atmosphere white dwarfs depend on the opacity of the Ly α and Ly β spectral lines. The opacity here is set by the strength and broadening of these lines; the latter is dictated by the far line wing, which is in the “quasi-static” limit of electron broadeni...
