VizieR Online Data Catalog: CaII and MgII excess flux density in cool stars (Rutten, 1987)
Abstract
The relation between the CaII H and K line-tore flux density and rotation period is studied for a sample of 313 cool stars of luminosity classes ranging from II-III to V, and compared to similar relations for MgII h and k and soft X-ray.
