Abstract | We propose a 50 ksec EPIC observation on Blanco 1, a metal rich high latitude open cluster, that for its characteristics is well suited to address somequestions unsolved by previuos X-ray missions.Our objective is to determine the X-ray luminosity of late type cluster members aiming to understand how metallicity affects stellar magneticactivity and its time evolution. The achieved sensitivity will allow us also to determine the low-mass end ofthe Initial Mass Function of Blanco 1, that for its peculiar origin could be very different from that of other more typical open clusters andstar formation regions. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
