BothEmden's/sup1 old hydrodynamic solar theory and the more modern thermo-hydrodynamical solar theory due to Bjerknes/sup2 lead to a higher temperature at the poles than at the equator of the sun. Bjerknes's theory is, ...

H- and auxiliary functions are tabulated for nonconservative scattering for phase functions of type p (Cos teta) = omega/sub0/ + omega/sub1/P/sub1/ (Cos teta) + omega/sub2/P/sub2/ X (Cos teta). They have been computed for ...

An analysis of the minimum-time data of AK Her and ER Ori revelas possible sinudodal variations in their orbital periods. In the case of AK Her we suspect two additional components; one of mass 0.2 to 0.4 MSun with a period ...

It is shown that the apparently flattened celestial vault can be represented by a geocentric sphere at a height of 3000-4000 km above the surface of the earth. It is also argued that our eye estimates the distance to this ...

We consider non-conservative Rayleigh scattering in finite atmospheres and study the polarization in the molecular lines both in the transmitted and reflected sunlight. We first investigate the parameterized models to ...

A study of all the available photoelectric times of minima of CM Lac, AB And and YY Eri does not reveal any changes in their orbital periods.
