cds-question@unistra.frx-ray-binary-starsWe present a Chandra X-ray observation of the X-ray bright E2 elliptical galaxy NGC 4649. In addition to bright diffuse emission, we resolve 165 discrete sources, most of which are presumably low-mass X-ray binaries. As found in previous studies, the luminosity function of the resolved sources is well-fitted by a broken power law. In NGC 4697 and NGC 1553, the break luminosity was comparable to the Eddington luminosity of a 1.4M_{sun}_ neutron star.2004ApJ...600..729Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/600/729CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)V/113 : Cataclysmic Binaries, LMXBs, & related objects (Ritter+, 2003)J/ApJ/599/218 : Chandra LMXB in NGC 4365 and NGC 4382 (Sivakoff+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/600/729https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/600/729http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/600/729https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/600/729https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/600/729http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/600/729GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/600/729/table1 (Discrete X-Ray sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/600/729/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/600/729/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/600/729/table1?GETtext/xml+votable180.050000true190.916708311.55327780.0055555555555555566/27907https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/600/729?format=asciiOpticaldefaultJ/ApJ/600/729/table1Discrete X-Ray sourcesrecnoRecord number assigned by the VizieR team.
