| Abstract | Using XMM-Newton we discovered that the complex of B stars known as Rho Oph arethe center of a 5-10 Myr old cluster. This cluster is located about 1 degreenorth of Lynds 1688, the embedded region of active star formation sometimesreferred to in the literature as the Rho Oph Cluster. Further analysis ofarchival WISE and ROSAT all sky survey indicates that there is additionalevidence of recent star formation in the vicinity of Rho Oph. These dataindicate that Rho Oph was the catalyst of multiple epochs of star formation,culminating 1 Myr ago with Lynds 1688. We propose to observe 2 fields to thenorth and west of Rho Oph. These data, combined with the WISE catalog willprovide a census of disked and diskless YSOs in one of the closest 5-10 Myr clusters to the Sun. |

| 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. |
