Title

NEW PLASMA DIAGNOSTICS USING RESONANCE LINES ON MCV PLASMA

Abstract

The scientific goal of this proposal is to demonstrate the NEW plasma diagnostics of ``optically-thin'' thermal plasma using the ``optically-thick'' resonance photons, since the later carries the information on the plasma shape. The minimal goal is to demonstrate the anisotropic radiative transfer of resonance photons of Fe-K line in the accretion column by the spin-phase-resolved high-resolution spectra with 50 ksec observation of V834 Cen. The ideal goals is to perform the independent measurement of the density using the resonance lines in 10% accuracy and to detect the multi-temperature structure of the accretion column and constrain the plasma shape using atomic lines of O, Mg, Si, S, and Fe with 100 ksec observation.
