cds-question@unistra.frmultiple-starsob-starsstellar-massesMassive binaries play an important role in fields ranging from gravitational- wave astronomy to stellar evolution. We provide several lines of evidence that classical OBe stars in the Small Magellanic Cloud (SMC) obtain their rapid rotation from mass and angular momentum transfer in massive binaries, which predicts that the subsequent supernovae should often eject OBe stars into the field. We find that (1) OBe stars have a higher field frequency than OB stars; (2) our cumulative distribution function (CDF) of stellar distances from O stars shows that OBe stars are indeed much more isolated than ordinary OB stars of corresponding spectral types; (3) the CDFs of OBe stars approach that of high-mass X-ray binaries (HMXBs), which are confirmed post-supernova objects; and (4) Oe stars are as isolated from clusters as Be stars, implying that their final masses are relatively independent of their initial masses, consistent with major mass transfer. Lastly, we also find that the spatial distribution of supergiant OBe stars differs from that of classical OBe stars, consistent with the different mechanisms responsible for their emission-line spectra.2022ApJ...936..112Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/936/112CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/23 : MK Classification for OB Stars (Lesh 1968)II/236 : UBVR CCD survey of the Magellanic clouds (Massey+, 2002)J/A+AS/102/451 : Emission-line stars and PNe in the SMC (Meyssonnier+ 1993)J/A+A/393/887 : SMC Be stars candidates (Mennickent+, 2002)J/MNRAS/353/601 : 2dF survey of the Small Magellanic Cloud (Evans+, 2004)J/AJ/127/1632 : UBVR(UIT) photometry of O and OB stars in SMC (Oey+, 2004)J/A+A/456/623 : VLT-FLAMES survey of massive stars (Evans+, 2006)J/ApJ/663/320 : IR-through-UV extinction curve (Fitzpatrick+, 2007)J/A+A/472/577 : NGC 330 Be stars and binaries (Martayan+, 2007)J/A+A/462/683 : Velocities in SMC field of NGC 330 (Martayan+, 2007)J/AJ/140/416 : IR photometry of massive stars in the SMC (Bonanos+, 2010)J/A+A/509/A11 : Ha emission-line objects in SMC clusters (Martayan+, 2010)J/MNRAS/424/1925 : Spectroscopic Binarity of O and B type stars (Chini+, 2012)J/other/Sci/337.444 : RV curves of Galactic massive O stars (Sana+, 2012)J/ApJ/763/101 : Massive field OB stars in the SMC (Lamb+, 2013)J/A+A/586/A81 : High-mass X-ray binaries in the SMC (Haberl+, 2016)J/ApJ/817/113 : RIOTS4 spectro survey of SMC field OB stars (Lamb+, 2016)J/A+A/624/A66 : Massive runaway and walkaway stars models (Renzo+, 2019)J/A+A/641/A42 : Main-sequence comp to massive Be stars (Bodensteiner+, 2020)J/A+A/634/A51 : NGC 330 seen by MUSE (Bodensteiner+, 2020)J/ApJ/903/43 : Kinematic & fundamental param OB stars (Dorigo Jones+, 2020)J/A+A/648/A65 : The sHRD of OB stars in NGC 2070 (Castro+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/936/112https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/936/112http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/936/112https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/936/112https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/936/112http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/936/112GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/936/112/table1 (Oey et al., 2004, J/AJ/127/1632 (OKP) Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/936/112/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/936/112/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/936/112/table1?GETtext/xml+votable180.050000true10.1171-73.54250.0055555555555555565/8323 8326 6/33297-33299 33316-33317 33319 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/936/112?format=asciidefaultJ/ApJ/936/112/table1Oey et al., 2004, J/AJ/127/1632 (OKP) Samplemup[11/81]?
