BeppoSAX observation of cen X-4 in quiescence

We report on a 61 ks BeppoSAX observation of the soft X-ray transient Cen X -4 during quiescence which allowed to study the source X-ray spectrum from similar to 0.3 keV to similar to 8 keV. A two-component spectral model was required, consisting of a black body with temperature of similar to 0.1 keV and a power law with photon index similar to 2. These values are compatibl e with earlier ASCA results indicating that Cen X-4 may be stable, within a factor of a few, over a 5 year baseline.
