In the early 1980s, our understanding of binary star evolution allowed us to construct a general evolutionary scenario which successfully explained the genesis of well-studied normal stars and offered potential explanation for new X-ray sources discovered in space experiments. ... At the present time it allows you to obtain evolutionary track of the close binary system with different parameters, which you determine yourself. ... To build your own track follow "Go to evolutionary track constructor". ...

Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...
