Abstract
The time-dependent problem of spectral line formation in a one-dimensional semi-infinite scattering and absorbing atmosphere containing a local energy source radiating equally in both directions is considered. The energy release is assumed to be non-stationary and to be either δ(t)-shaped
or of the unit jump form given by the Heaviside H(t) function. The main attention is paid to the
temporal dependence of the observed line profiles on the depth of energy eruption in the atmosphere.
The role of scattering in the continuous spectrum is emphasized.
