Abstract
The results of observations of 15 and 26 optical bursts detected during
June and July 1979 and June and July 1980, respectively, from the X-ray
burst source 4U/MXB 1636-53 in a 'white light' passband are presented.
The maximum burst fluxes above the persistent optical flux and
integrated burst fluxes are correlated, and it appears that the maximum
optical and X-ray burst fluxes are related according to a power law,
consistent with optical emission from blackbody reprocessing of X-rays.
The approximately linear relationship between the integrated optical and
X-ray burst fluxes argues against this simple picture. The correlation
of burst fluxes with waiting time since the previous burst suggests that
large optical bursts come after a long waiting time. Short burst
intervals observed both for optical and X-radiation suggest that not all
available nuclear fuel is consumed in the thermonuclear flash which
gives rise to the X-ray burst.
