| 英文摘要 | HW Vir-like eclipsing binaries are a group of detached binary systems that consists a very hot subdwarf B (sdB) type primary and a fully convective M-type secondary with periods shorter than 4 hours. Here we report the preliminary photometric study of the HW Vir-like binary NSVS14256825 based on our four years data. By analyzing the high precise BV(IR)(c) light curves of NSVS14256825 with the 2003 version of Wilson-Van Hamme code, we derived the mass ratio of this binary as q = 0.22. Assuming the mass of the primary component of NS14256825 is 0.46M(circle dot) the mass of its secondary component should be 0.1M(circle dot)(105M(Jup)) for the fully convective star. The O-C diagram of NS14256825 is shown here and the detail analysis is in progress. |
