ABSTRACT
Investigations of the relationship between stellar magnetic activity and rotation reveal the presence of a saturation threshold where, for unknown reasons, activity no longer varies with rotation period (Prot). However, these studies have focused on stars in young open clusters (<500 Myr) and field stars (2-10 Gyr). Measuring Prot and proxies for magnetic activity in older open clusters is essential to understand the evolution of the activity-rotation relation from the ZAMS to the age of field stars. We propose a snapshot X-ray survey of K and M dwarfs with measured Prot in the 650-Myr-old Hyades. By matching the resulting X-ray catalog to our catalog of 134 Hyades Prot, we will analyze the behavior of coronal activity as a function of Rossby number Ro at 650 Myr.

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
