Title X-Ray Plasma Diagnostics with RGS: A Bright T-Tauri Star in Sco Cen


DOI https://doi.org/10.5270/esa-6tz6ydk
Author Dr Mark Reynolds
Description We propose to observe a new X-ray bright T-Tauri star in Sco Cen (log10L_x 30.4 erg-s). The large flux makes this source a prime XMM-Newton-RGS target. We request a 65ks observation of Swift J122825.9-632100 with the RGS on XMM-Newton (50 ks goodtime & 15 ks flaring overhead). The proposed observations will detect the density and temperature sensitive Helium- like Ne IX and Mg XI triplets and place a stringent limit on the presence of O VII emission (f_{O VII} 2e-6 photons-s-cm^2), providing unique constraints on the accretion flow in this young stellar system.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
