ABSTRACT
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- day orbital period of the system. Taking into account the visibility gaps in the XMM orbit, we need to observe 2 contiguous orbital periods, giving a total exposure request of 300 ksec.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
