Abstract :We carried out spectroscopic analysis of the extracted stellar flare of the Algol binary system observed using the Suzaku satellite insert ignore into journalissuearticles values(OBSID: 401093010);, and resolved a strong 6.7 keV line emission. The 6.7 keV line emission of the Algol binary system is similar to the 6.7 keV line of the galactic ridge X-ray emission insert ignore into journalissuearticles values(GRXE);. The equivalent width insert ignore into journalissuearticles values(EW); compared favorably with the EW of the 6.7 keV emission line obtained from different galactic ridge regions. In the galaxy, we have a reasonable number of Algol binary systems and many other stars as strong coronal X-ray emitters characterized by frequent quiescent and super flaring phases as observed by Suzaku, and these systems could contribute to the 6.7 keV emission line from the galactic ridge.
