The Wilson-Bappu Effect for MG II K-Line Emission Widths
Published online by Cambridge University Press: 04 August 2017
Abstract
The existence of a tight linear correlation between the stellar absolute magnitude Mv and the Mg II k-line emission width log WMg II k (kms−1) is confirmed using IUE high-resolution (0.2A) data for 100 late-type stars. A least-squares fit to the data gives the relation:
