Spinning Stars and Stellar Secrets: A Look at Fast Rotators in Magellanic Cloud Clusters
This study found that many stars in four Magellanic Cloud clusters rotate extremely fast, with over 80% of stars in three clusters spinning near their break-up speed. By modeling how rotation affects star brightness and color, the researchers showed that rotation likely explains unusual features seen in star cluster diagrams, challenging previous ideas about age spreads.
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.
