| 摘要 | We present the preliminary results of photometric solutions of two EA type binaries (V192 and V239) in the southern globular cluster omega Cen. This is the first time to obtain photometric solutions of the two binaries. From our preliminary analysis we get that both the two binaries have very low mass-ratio, 0.139 for V192 and 0.085 for V239. Because of the low mass-ratio their secondary components are both very special objects and they are possibly horizontal branch stars. But they need more observation. |
