Demographics of triple systems in dense star clusters

摘要: Depending on the stellar type, more than $\sim 50$\% and 15\%$ of stars in field have at least one two companions, respectively. Hierarchical systems can be assembled dynamically dense star clusters, as a result few-body encounters among and/or compact remnants cluster core. In this paper, we present demographics compact-object triples formed via binary--binary \texttt{CMC Cluster Catalog}, suite simulations with present-day properties representative globular clusters (GCs) observed Milky Way. We show how initial host set typical orbital parameters formation times triples. find that typically assembles hundreds black hole (BH) inner binary, while only sufficiently small virial radii are efficient producing no BHs, BH-burning process. GC is expected to tens luminous component day. discuss Lidov-Kozai mechanism drive binary high eccentricities, whenever it takes place before triple reprocessed by encountering another member. Some these reach large eccentricities form variety transients sources, such blue stragglers, X-ray binaries, Type Ia Supernovae, Thorne-Zytkow objects, LIGO/Virgo sources.
