Double Compact Objects: Initial Conditions

All of the presented models and their properties are described in de Mink and Belczynski 2015

The naming of the files is as follows: submodel (A/B)_DCO type (NSNS/BHNS/BHBH). metallicity . dat. For example should you wish to view BHNS systems from submodel B for solar metallicity, you should choose the file: B_BHNS.02.dat. Each line contains information on one DCO. The format of the files is as follows:

Here is the list of events (strings) used by StarTrack to describe evolutionary history:
MTx - stands for nonconservative mass transfer through Roche lobe overflow. "x" indicates the relative component: 1-primary, 2-secondary.
SNx - stands for a supernovae explosion.
CEx(a0-b0:a1-b1) - stands for a common envelope events. "x" indicates the donor star: 1-primary, 2-secondary or 12-both components are donors. "a0-b0" are integer numbers indicating stellar types (explained below) of the primary-secondary components, respectively, at the start of the CE. Analogously "a1-b1" indicate stellar types at the outcome of the CE. For example "CE2(14-2:14-7)" means that a CE was initiated by the secondary component ("CE2"), which was a Hertzsprung gap star ("-2:"), onto the primary, which was a black hole ("14-"). In the outcome, the secondary ejected its hydrogen envelope and became a Wolf-Rayet star ("-7"), while the primary remained a black hole (":14-").
AICtypex indicates an accretion induced core collapse. "type" describes the compact object to which the progenitor has collapsed and "x" - the relevant component: 1-primary, 2-secondary. For example "AICNS1" means that the accreting primary star ("1") has collapsed into a neutron star ("NS").
