Rotational Velocities For B0-B3 Stars in 7 Young Clusters: Further Study of the Relationship between Rotation Speed and Density in Star-Forming Regions
TL;DR: In this article, the differences in rotation speeds between low and high density regions may reflect a combination of initial conditions and environmental effects: (1) the higher turbulent speeds that characterize molecular gas in high density, cluster- forming regions; and (2) the stronger UV radiation fields and high stellar densities that characterize such regions.

TL;DR: In this paper, the optical moving lines in spectra of the Galactic relativistic jet source SS433 spread over a twenty-year baseline from 1979 to 1999 were used to determine the apparent precession of the jet axis in SS433.

B Star Rotational Velocities in h and chi Persei: A Probe of Initial Conditions During the Star-Formation Process
TL;DR: In this article, the authors measured rotational velocities of 216 B0--B9 stars in the rich, dense h and chi Persei double cluster, and compared with the distribution of rotational velocity for a sample of field stars having comparable ages and masses, and found that both the higher rotation rates and the pattern of rotation speeds as a function of mass were likely imprinted during the star formation process.

Stellar Rotation: A Clue to the Origin of High-Mass Stars?
TL;DR: In this article, the authors examined projected rotational velocities among a large sample of newly formed stars spanning a range in mass between 0.2 and 50 M⊙ and search for evidence of a discontinuity in rotational properties that might indicate a difference in the stellar formation process at some characteristic mass.

B Star Rotational Velocities in h and χ Persei: A Probe of Initial Conditions during the Star Formation Epoch?
TL;DR: In this paper, the authors measured the projected rotational velocities of 216 B0-B9 stars in the rich, dense h and χ Persei double cluster and compared with the distribution of rotational velocity for a sample of field stars having comparable ages (t ~ 12-15 Myr) and masses (M ~ 4-15 M⊙).
