cds-question@unistra.frmagellanic-cloudsob-starsultraviolet-astronomyWe present projected rotational velocity values for 96 Galactic, 55 SMC, and 106 LMC O-B type stars from archival FUSE observations. The evolved and unevolved samples from each environment are compared through the Kolmogorov-Smirnov test to determine if the distribution of equatorial rotational velocities is metallicity dependent for these massive objects. Stellar interior models predict that massive stars with SMC metallicity will have significantly reduced angular momentum loss on the main sequence compared to their Galactic counterparts. Our results find some support for this prediction but also show that even at Galactic metallicity, evolved and unevolved massive stars have fairly similar fractions of stars with large Vsin i values. Macroturbulent broadening that is present in the spectral features of Galactic evolved massive stars is lower in the LMC and SMC samples. This suggests the processes that lead to macroturbulence are dependent upon metallicity.2009ApJ...700..844Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/700/844CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/236 : UBVR CCD survey of the Magellanic clouds (Massey+, 2002)III/147 : Studies of LMC stellar content (Rousseau+ 1978)J/PASP/121/634 : FUSE observations in Magellanic Clouds (Blair+, 2009)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/ApJS/144/21 : Galaxy and Magellanic Clouds OB and WR stars (Robert+, 2003)J/MNRAS/324/33 : MC WC/WO stars - Colliding winds (Bartzakos+ 2001)J/AJ/121/891 : UBV photometry of LMC OB associations (Parker+, 2001)J/AJ/119/2214 : Photometry of Magellanic OB associations (Massey+, 2000)J/MNRAS/284/265 : Rotational Velocities of 373 OB stars (Howarth+ 1997)J/ApJS/91/583 : MC massive stars IMF.
