Radial and rotational velocities, chromospheric activity and lithium abundances are presented for an X-ray-selected sample of stars in the young (220 Myr) open cluster NGC 6475. Low-mass members of the cluster have been identified on the basis of pho... Read More about Rotation, activity and lithium in NGC 6475.

On the initial-final mass relation and maximum mass of white dwarf progenitors (1997)
Journal Article

The four white dwarfs (WDs) discovered in the young open cluster NGC 2516 are crucial in defining the shape of the initial-final mass relation (IFMR) and upper mass limit for WD progenitors (Mwd). The cluster metallicity has been recently determined... Read More about On the initial-final mass relation and maximum mass of white dwarf progenitors.
