Why is the X-ray luminosity function different for the Hyades and Praesepe?
D. Barrado y Navascues, J. R. Stauffer, S. Randich
We have studied dF-dK and dM stars belonging to Praesepe in order to determine membership via radial velocities and to compare several stellar properties, such as X-ray luminositie…
