A photometric study of the contact binary XY Boo

The contact binary XY Boo is observed photoelectrically, and variations of the orbital period and the light curves are indicated. NewBV light curves and those of Binnendijk (1971) and Winkler (1977) are analysed by used of the light curve synthesis method. Combining the derived photometric elements with the spectroscopic elements of McLean and Hilditch (1983), we obtain values of the masses and the radii of the components of the system.     

The linke turbidity factor and Ångström coefficient in humid climate of Bahrain

By using solar spectrum intensity measurements, the aerosol optical depth and the atmospheric turbidity coefficients of Bahrain's atmosphere, i.e. the Linke turbidity factorT and Ångström coefficient, have been calculated at discrete wavelengths from 350 to 800 nm. A linear regression model was fitted forT versus for such a humid climate and it was compared to models reported for desert (Dhahran, Saudi Arabia) and temperate (Avignon, France) climates. A relationship between the linear regression slope,b, and the function of concentration and size distribution of particles,, over wide wavelength range was found.
