Formation of absorption lines in an inhomogeneous medium
Abstract
Fraunhofer lines asymmetry and its variations have been studied by means of convection, acoustic wave, and temperature fluctuation mechanisms. The present work analyzes Fraunhofer line profiles employing all these three mechanisms. Emphasis is placed on horizontal motions in a convective cell. An asymmetry value obtained theoretically is less than that of the observed one.
