Scientific paper

The problem of propagation of the disturbances from lowest to higher layers of stellar atmospheres is discussed in the framework of the dynamics of the ideal compressible gas with non-uniform temperature distribution. The conditions of "non-reflected" propagation of the acoustic - gravity waves are formulated. Following (Talipova et al, 2009; Grimshaw et al, 2010) the ordinary second-order differential equation for "non-reflected" sound speed profiles is derived. The obtained solutions can approximate the real observed vertical temperature profiles in the Sun atmosphere.
