Title Phase-resolved X-ray study of the accreting binary T Tauri star V4046 Sgr


DOI 10.5270/esa-4b8pkdf
Author Dr Thierry Montmerle
Description We propose to observe the ''twin binary.. T Tauri star V4046 Sgr, to look for phase-resolved, high- resolution spectroscopic signatures of magnetic accretion. All the detectors of XMM will be used, to get access to accurate densities, temperature, and elemental abundances of the plasma in the accretion shock region, and to characterize flare emission. With the RGS, we will be able to get elemental abundances resolved down to 1-10, and density-sensitive f-i ratios down to 1-4, of the 2.4- day orbital period of the system. Taking into account the visibility gaps in the XMM orbit, *we need to observe 3 contiguous orbital periods*, giving a total exposure request of 300 ksec.

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.
