Study On The ASAS Survey Data Is Based On The Physical Parameters Of The Contact Binary

In the Milky Way, more than half of the stars are binary systems. Binary is the "link" together by the universal gravity, orbiting each other, present a unique picture of evolution. In the binary system, intense star activities occur frequently in some binary star(star sunspot activity, flare, etc.) is called binary chromospheric activity,binary system of this kind of activity is of great significance for our research. Connect with binary physical parameters of the stars is not only a hot topic in the field of physics, is also the international celestial physics attaches great importance to research direction, and our team in China have been successfully carried out the research work in this field.In this paper, I first downloaded according to surveys from the ASAS contact binary data in the relevant data by solving the physical parameters of the most famous eclipsing binary tools(WD program) for physical contact binary parameters were calculated internationally, reuse Origin software for mapping, according to the final physical parameters and light curves obtained, analyzed and summarized. Second, I with our team in Chile to 60 cm telescope observations following binary 2MASS J21223350-4627383 and 2MASS J21222458-4619391, for example, using IRAF software to aperture photometry, the metering data through the WD application debugging, it is concluded that the two eclipsing binary photometric solution and have to go to the theoretical curve fitting of the light of the original curve, can be seen from the fitting result and the photometric solution is correct. In addition, I also draw this diagram two eclipsing binary. Finally, I conducted surveys ASAS photometric data and LAMOST spectroscopic survey data crossover study, found 214 ASAS inLAMOST database research conducted photometric eclipsing binary. And to identify the spectrum of these eclipsing binary has H? line emission, that is, there is a binary stellar chromospheric activity spectrum. By sorting out these spectra, for us to continue observing eclipsing binary research has guiding significance in the future.
