  Title: MULTI-WAVELENGTH STUDY OF THE QUIESCENT AND FLARING CORONA IN RZ CAS            


Abstract:
 We propose to observe the eclipsing Algol-type binary RZ Cas for 40 ks, providing
 the first full-orbit X-ray lightcurve with ASCA of an Algol-type system besides
 Algol. It will be possible to interpret the origin of the time variability
 previously found. The S/N ratio of the ASCA SIS spectrum will be sufficient to
 reliably determine the metal abundances and search for temperature and abundance
 variations on various timescales. By simultaneous ROSAT/HRI, IUE, optical, infrared
 (allocated) and VLA (proposed) observations, the temperature profile and spatial
 structure of the atmosphere can be deduced. In the case of a flare, unique time
 variability studies in the various spectral bands can be performed, and abundance variations can be investigated.
