Abstract
A very first light curve (LC) analysis of eclipsing binary ASAS 185542–0123.1 is presented. This star is part of our binary star survey project at Bosscha Observatory and also plays an important role as a testing ground for our new robotic telescope. LC of this star was constructed by using LEMON, a semi–automatic photometric pipeline written in Python. We managed to refine orbital period of this system and its time of primary minimum, hence we could update its ephemeris as Min I(HJD) = 2451964.551517 + 1.161607 × E. We also conducted a LC modeling with PHOEBE (PHysics Of Eclipsing BinariEs) software built on top of the widely used WD program. The photometry solutions are mass ratio q = 0.309 ± 0.026, orbital inclination i = 83.15 ± 0.42°, ratio of effective temperatures , and surface potentials for primary and secondary component Ω1 = 4.08 ± 0.16 and Ω2 = 2.71 ± 0.10, respectively. In conclusion, this system is classified as detached eclipsing binary system which has almost similar temperatures between its primary and secondary component. From temperature solution estimation, we have preliminary conclusion that its primary and secondary component has a spectral type of G0/1V + G2/3V, respectively.
