Scientific paper

Several pieces of circumstantial evidence are presented to disprove the conjecture that the gamma-ray luminosity of the binary Cygnus X-3 is fed by the rotational energy of a young and fast pulsar. It is contended that if the X-ray flux indeed results from accretion, then the possibility that the pulsar generates a strong wind comprising, among other things, a superstrong proton beam which is usually invoked to explain the ultrahigh energy gamma-ray observations from Cygnus X-3 seems to be an incongruity. It is argued that the idea that the pulsar in Cygnus X-3 is in fact an old recycled one fits neatly into the general framework of the evolution of X-ray binaries toward millisecond radio pulsars. It is suggested that the mass loss from a low-mass helium subgiant evolving on a nuclear time scale can be a viable way of attaining a prolonged mass transfer at a rate of more than about 10 exp -8 stellar mass/yr for short-period systems.
