1. Initial parameters of compact stars
Next: Other parameters of the Up: The Model Previous: Initial binary parameters . As we only deal with initially massive binary systems (their primary's mass is higher than 10 ), which are capable of evolving off the main sequence during less than years, the compact stars left behind stellar evolution are (in the case of the most massive stars) NSs and BHs. ... For a NS belonging to a binary, the evolution complicates as the secondary star evolves: for example, (recycling), etc. ...
