Reconstruction from Focal Volume Information a simultaneously recorded defocused image. An analysis of the full 3-dimensional interference pattern in the focal volume shows that this contains all the information that is needed for a determination of the object brightness distribution independent of atmospheric wavefront disturbances. Three di

Solar Granulation Speckle Interferometry Using Cross-Spectrum Techniquesrferometric techniques is reported here. The experiment consists of one-dimensional photoelectric scans of the solar surface, with the telescope diaphragmed into a slit aperture of 152cm x 3.2 cm to overcome the problem of foreshortening effects. Power spectra up to angular frequencies u of about 2

On Pressure Shifts of FeI Lines in Stellar Atmospheresive motion, and pressure broadening contribution is ussually neglected. Vince et al.(1985) showed that for detailed analysis of limb effect in solar NaI lines one should take into account the pressure shifts.

Pressure Broadening and Solar Spectral Line Bisectorsases, what is of interest especially for the solar granulation studies, bisectors for NaI 3s. S-np. P° solar lines have been calculated for different positions on the solar disk. Our numerical results clearly demonstrate that in the case of the examined spectral series the influence of pressure broa

Line Shifts In The Infrared Spectra Of Late-Type Stars and magnetic field generating mechanisms below the photosphere (Sofia and Endal 1987), and because of its role in the energy transport through the atmosphere. The study of convective motions in red giants in particular, on which little has been done, could help to understand such phenomena as the i

Asymmetry of Absorption Lines in the Solar and Procyon Sprectaectral line bisectors is given on the basis of the theoretical inhomogeneous models of their atmospheres and also on the basis of stochastic approximation theory of spectral line formation. The conclusion is made that the main differences between the Sun and Procyon are caused by the differences of
