Abstract Optical radiation is emitted from an accretion disk which is irradiated by X-rays. In the outer part the disk is heated mainly by X-rays, and its scale height is greater than that without X-ray heating. Hence the outer region in which X-ray heating is dominant gives a main contribution to optical emission. Since the temperature in this region is several times 104 K, optical emission is roughly explained by the Rayleigh-Jeans law. When the X-ray source emits an X-ray burst, the disk also emits an optical burst with some time delay. This explains the time profile of an optical burst with respect to that of an X-ray burst, as observed for MXB 1636 - 536.
