    PR # 31029                                                                   
     We propose to observe a cluster of protostars in NGC1333 star forming       
      cloud with ASCA satellite. Hard X-ray imagin with enough integration       
      time of 100ksec will effectively pick up deeply embedded protostars        
     in this region, which contains at least 5 bright protostar candidates       
     .  Hardness ratio or spectrum of a detected source will help us judge       
      whether it is a protostar or not. The anticipated data will provide        
     us some informations on hidden central star of protostar.
