cds-question@unistra.frx-ray-binary-starsgalaxiesBased on a homogeneous set of X-ray, infrared and ultraviolet observations from Chandra, Spitzer, GALEX and 2MASS archives, we study populations of high-mass X-ray binaries (HMXBs) in a sample of 29 nearby star-forming galaxies and their relation with the star formation rate (SFR). In agreement with previous results, we find that HMXBs are a good tracer of the recent star formation activity in the host galaxy and their collective luminosity and number scale with the SFR, in particular, LX~~2.6x10^39^SFR. However, the scaling relations still bear a rather large dispersion of rms~0.4dex, which we believe is of a physical origin. We present the catalog of 1057 X-ray sources detected within the D25 ellipse for galaxies of our sample and construct the average X-ray luminosity function (XLF) of HMXBs with substantially improved statistical accuracy and better control of systematic effects than achieved in previous studies. The XLF follows a power law with slope of 1.6 in the log(LX)~35-40 luminosity range with a moderately significant evidence for a break or cut-off at LX~10^40^erg/s. As before, we did not find any features at the Eddington limit for a neutron star or a stellar mass black hole. We discuss implications of our results for the theory of binary evolution. In particular we estimate the fraction of compact objects that once upon their lifetime experienced an X-ray active phase powered by accretion from a high mass companion and obtain a rather large number, fX~0.2x(0.1Myr/{tau}x) ({tau}x is the life time of the X-ray active phase). This is about 4 orders of magnitude more frequent than in LMXBs. We also derive constrains on the mass distribution of the secondary star in HMXBs.2012MNRAS.419.2095Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/419/2095CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cb : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/419/2095https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/419/2095http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/419/2095https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/419/2095https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/419/2095http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/419/2095GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/419/2095/hmxb (High-mass X-ray binaries Catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/419/2095/hmxb?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/419/2095/hmxb?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/419/2095/hmxb?GETtext/xml+votable180.050000true13.0183147.551150.0055555555555555566/2687 3389 5966 5995 6034 6040 6042 6081 7424 7606 7741 7743 8225 10761 10901 10905 11026-11027 11180 11432 11434 16441 18212 18895 20720 25344 28631 33193 33920-33921 34533 35576 43874 45912 45914https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/419/2095?format=asciiOpticaldefaultJ/MNRAS/419/2095/sfgalSample of nearby star-forming galaxies resolved by ChandrarecnoRecord number assigned by the VizieR team.
