cds-question@unistra.frglobular-star-clustersblack-holesmultiple-starsx-ray-sourcesUsing X-ray sources as sensitive probes of stellar dynamical interactions in globular clusters (GCs), we study the mass segregation and binary burning processes in {omega}Cen. We show that the mass segregation of X-ray sources is quenched in {omega}Cen, while the X-ray source abundance of {omega}Cen is much smaller than other GCs, and the binary hardness ratio (defined as L_X_/L_K_f_b_), with fb being the binary fraction, L_X_ and L_K_ being the cumulative X-ray and K-band luminosity of GCs, respectively) of {omega}Cen is located far below the L_X_/L_K_f_b_)--{sigma}_c_ correlation line of the dynamically normal GCs. This evidence suggests that the binary burning processes are highly suppressed in {omega}Cen, and other heating mechanisms, very likely a black hole subsystem (BHS), are essential in the dynamical evolution of {omega}Cen. Through the black hole burning processes (i.e., dynamical hardening of the BH binaries), the BHS is dominating the energy production of {omega}Cen, which also makes {omega}Cen a promising factory of gravitational-wave sources in the Galaxy.2020ApJ...904..198Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/904/198CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/195 : Globular Clusters in the Milky Way (Harris, 1996)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/ApJ/697/224 : Chandra X-ray sources in {omega} Cen (Haggard+, 2009)J/ApJ/710/1032 : Proper motions in {omega} Cen (Anderson+, 2010)J/ApJ/827/12 : HSTPROMO cat.
