| Abstract: |
We present the preliminary results of photometric solutions of two EA type binaries (V192 and V239)
in the southern globular cluster ω 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. |
