Abstract
A new analytical solution describing a time-dependent disk in a binary syst em at outburst. which has a fixed tidal ly-truncated outer radius, is appli ed to 1975 X-ray nova burst of A0620-00, The X-ray flux of a multicolor (bl ack-body) alpha -disk decays quasi-exponentially with time. Modeling the X- ray and the optical light curves of A0620-00. we can estimate ce and obtain 'distance-mass of compact object' relation.
