    PR # 32020                                                                   
     The flare star, Gliese 890, is an active single M dwarf (BY Dra type        
     variable) in the solar neighborhood with a very short period of             
     rotation (10.5h).  We propose to observe this young disk star with          
     ASCA, over its one full rotation period, so as to determine its X-ray       
      spectral characteristics and to study its coronal spectrum as a func       
     tion of rotational phase.  We will determine the temperature structur       
     e of its corona, distinguish between multiple discrete components and       
      a continuum of temperatures, and estimate the elemental abundances i       
     n its corona.  We will look for possible spectral variability due to        
     rotational modulation of compact emissionregions and/or of cool, abso       
     rbing clouds that may be present and might occult underlying coronal        
    structure
