Beginning of ReadMe : J/A+A/421/175 XMM sources in Blanco 1 (Pillitteri+, 2004) ================================================================================ XMM-Newton observations of the young open cluster Blanco 1. I. X-ray spectroscopy and photometry. Pillitteri I., Micela G., Sciortino S., Damiani F., Harnden F.R.JR <Astron. Astrophys., 421, 175-186 (2004)> =2004A&A...421..175P ================================================================================ ADC_Keywords: Clusters, open ; X-ray sources Keywords: X-ray: stars - stars: activity - Galaxy: open clusters and associations: individual: Blanco 1 Abstract: We present an X-ray study of the high metallicity young open cluster Blanco 1 based on XMM-Newton data. X-ray spectroscopy of cluster members is presented for the first time as well as new X-ray distribution functions of late-type stars. We detected all known dF and dG stars in the EPIC field and 80% and 90% of dK and dM stars, respectively. The X-ray spectral analysis of the X-ray brightest cluster stars and X-ray color analysis of a larger sample show that a model with two temperatures (at about 0.3 and 1keV) explains the quiescent activity phase spectra. We discuss also the nature of unidentified X-ray sources in the observed region and their X-ray spectral properties. Description: The observation studied here was performed with the XMM-Newton satellite in June 2002 during revolution 0461 with a nominal duration of 50ks.
