| Abstract: | The profiles of hydrogen Lyman-alpha line in an expanding spherical atmosphere containing dust and gas were calculated. The variation of equivalent widths with velocities of expansion of the atmosphere, together with the amount of dust present in the medium is being investigated. Curves of growth have been drawn for different velocities and dust optical depths. |
