The MG II emission in BD -0 4234

Rucinski, S. M.

Abstract

The strength of the Mg II emission in this metal-poor, high-velocity binary consisting of synchronized K-type dwarfs follows the same extension of the dependence on the inverse Rossby number which holds for rapidly-rotating Population I stars. This result indicates that the efficiency of the dynamo mechanism might be independent of metal abundance.
