Spinning Stars: Exploring Rotation Across Stellar Spectral Types

This study examines how stellar rotational velocity varies with spectral type and evolutionary stage. Using data from nearly 50,000 stars, it finds that hot stars (O0 to F2) rotate faster than cool stars (F2 to M9), with rotation slowing significantly as stars evolve. Magnetic braking and stellar winds are key factors in this decline, highlighting how rotation influences a star's lifecycle.
