Abstract | GT- The open cluster NGC 188 is one of the oldest cluster in the Galaxy. Itsrichness and location relatively far from the galactic plane is such that mostof its stellar sources will be in the EPIC field of view with few field starsand low interstellar absorption. Compared to most open clusters, NGC 188 ispotentially as old as the disk which makes NGC 188 of substantial interest interm of stellar evolution. The present study will characterize the X-ray stellaremission of NGC 188 stellar populations in particular by measuring the X-rayspectra on W Ursae Major binaries and FK Comae objects and by establishing theHR location of X-ray coronal emission among G and K giants. |

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. |
