| Summary: | The close binary system ES Librae is an eclipsing binary with 0.4 variability of V magnitude. ES Librae is also a single-lined spectroscopic binary that was observed by Irfan (2006) at Bosscha Observatory to obtain radial velocity curve. Photometric observation was carried out on June-August 2016 at Bosscha Observatory. We used Celestron C8 (D=203.2 mm, F/10) as collector and CCD SBIG ST7XME (756x510 pixels, 9x9 ?m) as detector with standard photometric Bessel BVRI filters. The light curve and radial velocity curve are analyzed to derive the absolute parameters and the model of ES Librae. We purpose ES Librae is a semidetached near-contact binary. The evolutionary status will be discussed. |
