Extract

On our way to calculating model stellar photospheres (next chapter), we need to study the continuous absorption.The main contributors are neutral hydrogen for hotter stars and the negative hydrogen ion for cooler, solar-type, stars.The physics and equations are developed for calculating the continuous absorption coefficient as it is needed in the solution of the transfer equation.
