Angular momentum is a key property regulating star formation and evolution. However, the physics driving the distribution of the stellar rotation rates of early-type main-sequence stars is as yet poorly understood. Using our catalog of 40,034 early-type stars with homogeneous vsini parameters, we review the statistical properties of their stellar rotation rates. We discuss the importance of possible contaminants, including binaries and chemically peculiar stars. Upon correction for projection… Expand

Stellar Rotation in Young Clusters. I. Evolution of Projected Rotational Velocity Distributions
Open clusters offer us the means to study stellar properties in samples with well-defined ages and initial chemical composition. Here we present a survey of projected rotational velocities for aExpand
On the Rotational Evolution of Solar- and Late-Type Stars, Its Magnetic Origins, and the Possibility of Stellar Gyrochronology*
We propose a simple interpretation of the rotation period data for solar- and late-type stars. The open cluster and Mount Wilson star observations suggest that rotating stars lie primarily on twoExpand
Rotational velocities of A-type stars - IV. Evolution of rotational velocities
Context. In previous works of this series, we have shown that late B- and early A-type stars have genuine bimodal distributions of rotational velocities and that late A-type stars lack slow rotators.Expand
The VLT-FLAMES survey of massive stars: atmospheric parameters and rotational velocity distributions for B-type stars in the Magellanic Clouds
We provide atmospheric parameters and rotational velocities of a large sample (~400) of O- and early B-type stars, analysed in a homogeneous and consistent manner, for use in constraining theoreticalExpand
Effects of Metallicity on the Rotational Velocities of Massive Stars
Recent theoretical predictions for low-metallicity massive stars predict that these stars should have drastically reduced equatorial winds (mass loss) while on the main sequence, and so should retainExpand
Angular Momentum Transport in Stellar Interiors
Stars lose a significant amount of angular momentum between birth and death, implying that efficient processes transporting it from the core to the surface are active. Space asteroseismologyExpand
Rotational velocities of A-type stars. III. Velocity distributions
Aims. A sample of $v\sin i$ of B9 to F2-type main sequence single stars has been built from highly homogeneous ${v\sin i}$ parameters determined for a large sample cleansed of objects presenting theExpand
Examining Disk-Regulated Rotation: The Rotation Period Distribution of Pre-Main Sequence Stars In and Around the Orion Nebula
We report rotation periods for 254 stars in an area 40' × 80' centered on the Orion Nebula. We show that these stars are likely members of the young (~106 yr) Orion OBIc/d association. The rotationExpand
An investigation of the rotational properties of magnetic chemically peculiar stars
The magnetic chemically peculiar (mCP) stars of the upper main sequence exhibit strong, globally organized magnetic fields that are inclined to the rotational axis and facilitate the development ofExpand
On the origin of the bimodal rotational velocity distribution in stellar clusters: rotation on the pre-main sequence
We address the origin of the observed bimodal rotational distribution of stars in massive young and intermediate age stellar clusters. This bimodality is seen as split main sequences at young agesExpand
