Abstract

We present the physical parameters of an eclipsing binary system EPIC 211982753 derived through photometric and radial velocity data modeling. We make use of photometric data from NASA’s K2 mission, ASAS-SN, and 1.3-m Devasthal Fast Optical Telescope (DFOT) while spectroscopic data have been acquired from the HERMES spectrograph at 1.2-m Mercator telescope. The linear ephemeris for the system is updated using the K2 mission data. The synthetic lightcurve and radial velocity curves are generated with the help of eclipsing binary modeling package PHOEBE 1.0. The masses of primary and secondary components are determined as 1.64 ±0.02 and 1.55 ±0.01 M, respectively. The radius for primary and secondary components are estimated as 1.73 ±0.02 and 1.47 ±0.02 R, respectively. The distance of the system is calculated as 238 ± 4 pc. The eclipsing binary is found to be a total eclipsing system with a high mass ratio of q=0.94.
