摘要：
We present the photometric analysis of three short-period eclipsing binaries (EBs), which have been monitored through the 1.3-m Devasthal Fast Optical Telescope (DFOT), Nainital. The two sources 2MASS J152450+245943, 2MASS J163321+543928 were observed in the B, V and Ic- band with 2k×2k CCD and the third source CRTS J163720+172047 was observed with 512×512 CCD in V, Rc and Ic-band. All three systems are found to be double contact eclipsing binaries. The PHOEBE software based on theWilson-Devinney (WD) code is used for the analysis of the photometric light curves. The mass ratios are found to be 0.97, 0.75 and 0.81 for 2MASS J152450+245943, 2MASS J163321+543928 and CRTS J163720+172047, respectively. The orbital inclinations are estimated to be ∼ 74:5o;∼ 49:3o and ∼ 60:0o for 2MASS J152450+245943, 2MASS J163321+543928 and CRTS J163720+172047, respectively. © 2019 Societe Royale des Sciences de Liege.
