Origins and ages of X-ray-luminous dwarf M stars.
Abstract
The nearby M dwarfs for which published X-ray data are available are assembled and examined for kinematical and other evidence of their age. Those with the highest order of X-ray luminosity are presumably young, but subsets of them fall kinematically into old disk as well as young disk populations. The youthful "old disk" M dwarfs may have formed recently in the interstellar high-velocity clouds or intermediate-velocity clouds from which they derive their kinematical properties.
