Angular Momentum Loss and Chromospheric Activity in Late-Type Dwarfs
Published online by Cambridge University Press: 04 August 2017
Extract
A chromospheric color-magnitude diagram has been constructed from the Vaughan-Preston survey of Ca II emission among solar neighborhood stars. The relative flux in the H and K lines declines with mass on the lower main-sequence as a consequence of the decline of the ZAMS rotational velocity with mass. The features of this C-M diagram are discussed, and some evidence for a gap in the distribution of Ca II emission with age is examined.
