The X-ray Luminosity Distributions of the high-metallicity open cluster Blanco 1.

PILLITTERI I., MICELA G., SCIORTINO S. and FAVATA F.

Abstract (from CDS):

We present X-ray Luminosity Distributions (XLDs) of late-type members (dF, dG, dK, dM) of the Blanco 1 cluster, based on ROSAT-HRI data and new astrometric-photometric membership obtained from the GSC-II project. For the first time we present the XLD of dM stars of this cluster. The high metallicity of Blanco 1 allows us to investigate the role of chemical composition on the coronal emission of late-type stars. Comparison between X-ray Luminosity Distributions of Blanco 1 and Pleiades, NGC 2516 and α Per suggests a possible metallicity effect in dM stars.
