Abstract

A new analytical solution describing a time-dependent disk in a binarysystem at outburst, which has a fixed tidally-truncated outer radius,is applied to 1975 X-ray nova burst of A0620-00.The X-ray flux of a multicolor (black-body) α-disk decaysquasi-exponentially with time.Modeling the X-ray and the optical light curves of A0620-00, we canestimate α and obtain `distance–mass of compact object' relation.
