Abstract
The evolution of a binary system with components of 10M ⊙ and 8M ⊙ is computed through a case B of mass exchange. It is found that after the end of core helium burning, a second stage of mass transfer from the primary occurs. Carbon ignition is prohibited by the large neutrino losses in the degenerated core. The primary remnant, a 1.12M ⊙ star, ends as a white dwarf. A comparison with the 10M ⊙ single evolution is made.
