The optical light curves of XTE J2123--058: the mass of the binary components and the structure of the quiescent accretion disk

T. Shahbaz, C. Zurita, J. Casares +4

We present optical photometry of XTE J2123-058 during its quiescent state taken in 1999 and 2000. The dominant feature of our R-band light curve is the ellipsoidal modulation of th…
