The spectral distribution of energy for 21 early K-stars in the wavelength region 450 nm to 750 nm at a definition of 5 nm have been obtained. A two dimensional photometric spectral classification index-system for these stars has been devised and dis

The dependence of mass ratio of eclipsing binary systems on period has been studied. It has been found that semi-detached systems obey the relationm2/m1=0.64–0.079P orm2/m1=0.29–0.028P depending upon whether the mass ratio is >0.3 or

WHEN, last May, Comet Arend–Roland became a bright naked-eye object in the northern hemisphere, we carried out a series of photoelectric measures of the polarization of its coma at different phase angles. The technique employed utilized a piece of
