cds-question@unistra.frearly-type-starsline-intensitiesStellar rotation is an important parameter in the evolution of massive stars. Accurate and reliable measurements of projected rotational velocities in large samples of OB stars are crucial to confront the predictions of stellar evolutionary models with observational constraints. We reassess previous determinations of projected rotational velocities (vsini) in Galactic OB stars using a large, high-quality spectroscopic dataset and a strategy that accounts for other sources of line-broadening in addition to rotation. We present a versatile and user-friendly IDL tool - based on a combined Fourier transform (FT) + goodness-of-fit (GOF) methodology - for the line-broadening characterization in OB-type stars. We used this tool to (a) investigate the impact of macroturbulent and microturbulent broadenings on vsini measurements, and (b) determine vsini and the size of the macroturbulent broadening (v_m_) in a sample of ~200 Galactic OB-type stars.2014A&A...562A.135Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/562/A135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/6 : OB stars in Milky Way (Lynga, 1964)V/31 : Kinematic data for O-B5 stars (Rubin+, 1962)J/ApJ/454/151 : OB Associations of the Northern Milky Way (Massey+ 1995)J/A+AS/118/481 : ROSAT all-sky survey catalogue of OB stars (Berghoefer+ 1996)J/MNRAS/284/265 : Rotational Velocities of 373 OB stars (Howarth+ 1997)J/A+AS/137/113 : Walraven photometry of OB stars (van Houten+, 1999)J/A+A/369/527 : Walraven photometry of OB stars (van Houten, 2001)J/ApJS/161/154 : Near-IR spectral atlas of OB stars (Hanson+, 2005)J/A+A/597/A22 : Massive O- and B-type stars velocities (Simon-Diaz+, 2017)J/A+A/613/A65 : Spectroscopic parameters of O-type stars (Holgado+, 2018)J/A+A/613/A9 : Extinction towards Galactic O stars (Maiz Apellaniz+, 2018)J/A+A/639/A157 : Massive O-type stars near ZAMS elusive detectionhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/562/A135https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/562/A135http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/562/A135https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/562/A135https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/562/A135http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/562/A135GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/562/A135/tablea (Results from the IACOB-broad analysis (tables A1-A5))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/562/A135/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/562/A135/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/562/A135/tablea?GETtext/xml+votable180.050000true36.695792858.87586640.0055555555555555566/1198 1293 1297 1299 1303 1323 1332 1555 1558 1790 1929 1946 2409 2947 2970 3011 3051 3054 3060 3066 3214 3231 3245 3247 3249 3251 3256-3258 3260-3261 3272 3301 3307 3315 3384 3430 3585 3600 3622 3653 3785 5506 6891 12943 13001 13255 13557 13953 13984 13999 14008 14179 14197 14240 14283 14305 14431 14456 14459 14630-14631 14643 14645-14647 14653-14654 14712 14734 14740-14741 14743 14745 14824-14825 15369 15476 15573 15577 15631 15656 15672 15677 15682-15683 15745 15747 20810 20834 20860 20915 20974 21401 21432 21434-21436 21438-21439 21530-21531 21635 21638 21655-21656 22033 22088 22211 22216 22223 22240 22243 22246 22249 22253 22264 22772 22805 22854 22859 22862 22884 22888-22889 22893 22907 23007 23360 23637 23714 23717 23774 23962 23979 23982 24179 24370 24496 25002 25993 26929 27498 28890-28892 28900 28913 28915 29025 29036 29089 29091 29095 29115 29158 29162 29463 29513 29530 29600 29893 30818 31748 32174 39894 39907 39930 40617 42924 42977 44366 44389 44717https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/562/A135?format=asciiOpticaldefaultJ/A+A/562/A135/tableaResults from the IACOB-broad analysis (tables A1-A5)LineLine namephys.atmol.elementcharrecnoRecord number assigned by the VizieR team.
