Procyon and Capella systems cannot produce Type Ia supernovae because they are not binary systems capable of generating such explosions. Procyon consists of a main sequence star, Procyon A, and a white dwarf companion, Procyon B, with an average separation of 15 AU. The distance between the stars is too great for Procyon A to transfer mass to Procyon B effectively, preventing a potential supernova event. Procyon A will eventually become a red giant, but its mass is insufficient to trigger an explosion in Procyon B, which is only 0.6 solar masses. Therefore, these systems will not experience a Type Ia supernova in the foreseeable future.
