Tschape & Rudiger 2001 review

Rotation-induced Lithium Depletion of Solar Type Stars in Open Stellar Clusters


purpose: test the correlation between Li-abundance and rotation period for solar type (G0-K0) stars


Introduction

  • It seems that rapidly rotating stars have more lithium than slower stars (of the same mass)
  • slower rotators more efficiently transport Li to the inner layers of the star to be processed
  • faster rotators have more Li stuck in their outer layers for longer
Observations
  • Data taken from Prosser-Stauffer archive of stars in open clusters
  • when solar type stars were targeted, plots of [Li] vs Prot showed a clear correlation
