Light curves of short period eclipsing binary stars. (Senior Division).The periods for many Algol eclipsing binary stars eclipsing binary star: see binary star; variable star. , two stars orbiting each other, have not been updated since 1950. Analysis of the light curves of the eclipsing binary stars can determine a more accurate period for the star system. This research is divided into three sections: the observation, reduction and analysis of light curves. In the observational section, six eclipsing binary star systems are selected and CCD CCD
in full charge-coupled device
Semiconductor device in which the individual semiconductor components are connected so that the electrical charge at the output of one device provides the input to the next device. images are taken of the selected stars over six night observing sessions using a 24-inch telescope. The reduction of the data includes noise reduction and flattening
The flattening, ellipticity, or oblateness of an oblate spheroid is the "squashing" of the spheroid's pole, down towards its equator. . It also includes the process of collecting the counts produced by the star in each image, which are then converted to magnitudes. The last part of the process is the production of light curves for each star, which provides information on the period, mass, and radii ra·di·i
A plural of radius.
a plural of radius of the eclipsing binary star. The observation and reduction processes of this research are complete and prove to be reliable. Through the analysis of the light curve for the star GW Tau a more accurate period is being determined.
