Photometric study of a marginal contact binary SY Hor
No full text32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYIn this study, we present light curve analysis of a southern contact binary SY lior. Photometric parameters of the system and its components are derived using the Wilson and Devinney code based on the data taken from the SuperWASP public data archive. Photometric solutions indicate that SY Hai is a marginal contact binary system with a mass ratio of q = 1.59 and a contact degree of f = 6%.Turkish Phys So
Geomagnetic and solar cycle dependence of the ring current ions
No full textObservations obtained from CRRES/MICS in the solar maximum show that both the ring current composition and the location of the maximum ion flux can be influenced by geomagnetic activity and solar cycle. Both the number and the energy density ratio of O+, He++ and He+ ions increase during geomagnetic active times, whereas that of H+ exhibits an obvious decrease. It is also interesting to compare with AMPTE observations which were made in the solar minimum. The abundance of the ring current H+ is apparently lower in the solar maximum than in the solar minimum. In contrast, the abundance of both O+ and He++ ion is higher in the solar maximum. In addition, the average location of the maximum number density of the energetic ions is about 0.5 R-E lower in solar maximum than that in solar minimum.Astronomy & AstrophysicsCPCI-S(ISTP)
