cds-question@unistra.frgalaxiesglobular-star-clustersgalaxy-classification-systemsapparent-magnitudeWe investigate the relationship between low-mass X-ray binaries (LMXBs) and globular clusters (GCs) using United Kingdom Infrared Telescope (UKIRT) observations of M31 and existing Chandra, XMM-Newton and ROSAT catalogues. By fitting King models to these data, we have estimated the structural parameters and stellar collision rates of 239 of its GCs. We show a highly significant trend between the presence of a LMXB and the stellar collision rate of a cluster. The stellar collision rate is found to be a stronger predictor of which clusters will host LMXBs than the host cluster mass. We argue that our results show that the stellar collision rate of the clusters is the fundamental parameter related to the production LMXBs. This is consistent with the formation of LMXBs through dynamical interactions with little direct dependence on the neutron star retention fraction or cluster mass.2009MNRAS.392L..55Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/392/L55CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/471/127 : New globular clusters in M 31 (Galleti+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/392/L55https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/392/L55http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/392/L55https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/392/L55https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/392/L55http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/392/L55GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/392/L55/table1 (K-band magnitude and structural parameters for 239 globular clusters (GCs) in M31)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/392/L55/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/392/L55/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/392/L55/table1?GETtext/xml+votable180.050000true9.962487540.96958330.0055555555555555566/2619 2622-2623 2666-2667 2705 2707-2709 2752https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/392/L55?format=asciiOpticaldefaultJ/MNRAS/392/L55/table1K-band magnitude and structural parameters for 239 globular clusters (GCs) in M31W0Central potential depthstat.paramfloatrecnoRecord number assigned by the VizieR team.
