Abstract
Lyman-band absorption of H2, when compared with the combined opacity of H, CI, MgI, and SiI, has been found to contribute significantly to the total opacity in the range 912-1900 Å in the solar atmosphere. Inclusion of Lyman-band absorption in the solar model may reduce chromospheric temperature from that given by Gingerich et al. and improve agreement between observed and calculated extreme-ultraviolet and microwave intensities. The Lyman-band absorption may also be important in stars as hot as A0.
