    PR # 32004                                                                   
     The Silicon stars HR 5624 and $\nu$ For are known X-ray emitters,           
     with X-ray luminosities log Lx of 29.8 and 29.4 in the PSPC energy          
     range. Drake et al.  (1994) have argued that they are the prototypes        
     of a new class of magnetospheric X-ray emitters. If they are                
     intrinsic X-ray sources, then the Si line at 1.9 keV will be a              
     dominant spectral feature. Indeed, a previous PSPC spectrum of HR           
     5624 that we obtained can be well-fit by an isothermal plasma with Si       
      having 22 times the solar abundance. However, it can be nearly as          
      well-fit by a model with two solar-abundance components of differing       
      temperatures. 50 ksec ASCA observations of these 2 stars will              
      definitively resolve this ambiguity, and confirm or refute the             
     existence of this proposed cl
