Scientific paper

This catalogue contains the data needed to follow-up the liberal evolution of binaries with a B-type primary at birth. Loss of mass and angular momentum is included according to the scenario as outlined in the paper.
Tables are labeled with: * Mass of the initial primary in solar masses * Type of tidal interaction ("strong" or "weak") or conservative evolution ("conser")
For example: "09strong" signifies an initial 9 solar mass primary and strong tidal interactions (fsync=0.1), while "09weak" signifies weak tidal interactions (fsync=1.0). "09conser" assumes conservative evolution.
When systems evolve conservatively, the evolutionary path does not depend on the type of tidal interaction. Therefore, in the case of 3 and 4 solar mass primaries, only the "conser" tables are given. Binaries with a 5 solar mass primary evolve almost conservatively, with very small differences between strong and weak tides. The table "05strong" contains mostly conservative calculations, and only the strong assumption if mass is lost from the system. At 6 solar mass primaries and above, "conser" tables are always given for comparison.
Each table contains the evolutionary tracks for multiple combinations of the initial mass ratio and orbital period. The beginning of each evolution is characterized by a step=1. The tables start with the lowest mass ratio and the lowest orbital period, running through increasing periods before going to higher mass ratios.
