Scientific paper

The evolution of a binary system consisting of 1 solar mass neutron star and a 25 solar mass blue supergiant through a phase of common envelope is investigated. The effects of an additional energy source on the supergiant's envelope, due to the presence of the neutron star, and variable mass loss from the system, taken as proportional to the total luminosity are included. The results indicate that, independently of the initial period, the system loses its whole envelope as a consequence of the common envelope phase, the final product of this being a detached system, consisting of a neutron star and a helium star.
