Discovery of the hot companion to the two-day cepheid HD 129708.
Arellano Ferro, A.; Madore, B. F.
The Cepheid HD 129708 has been observed with the International Ultraviolet Explorer satellite, and a hot companion star (B4-5) has been discovered. Comparison of the observed energy distribution with theoretical atmosphere models gives Te = 16,000±1000K and log g = 4.0±0.5 for the hot companion. A visual magnitude difference ΔV = 2…
The MG II emission in BD -0 4234
Rucinski, S. M.
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.

Psi 3 PISCIUM and the rotation-activity connexion
Williams, D.; Stickland, D. J.
IUE observations of the rapidly rotating G0 III star ψ3 Psc and a number of RS CVn systems, together with data from the literature, have been studied to clarify the relationship between axial rotation and chromospheric activity.
