| ABSTRACT | |
| We propose to obtain a complete X-ray census for the stellar association Volans-Carina. This kinematically defined co-moving (and thus joinly born) group of stars has a critical age (~ 90 Myr) for our understanding of the secular decay of X-ray activity, and is uniquely close (~ 85 pc) such that all its low-mass members (down to ~ 0.1 M_sun) can be detected with XMM-Newton. This survey complements eROSITA measurements at the faint low-mass end of the stellar mass sequence, and crucially allows us to address the mass-dependent age-decay of coronal activity which constrains the stellar dynamo and the evolution of planet atmospheres. | |
