Lithium and chromospheric activity in the Alpha Persei cluster

We have obtained high resolution spectra of a set of proposed members of the Alpha Persei open cluster which had previously been shown to have anomalously low lithium abundances. We have used the new spectra to derive Ca II emission strengths, radial velocities, and reddening estimates in order to a...
