Abstract

We present the analysis of archival Chandra high resolution X-ray spectra of AM Her. Emission lines from several hydrogen-like ions, helium-like ions, Fe-L shell transitions and Fe-K fluorescent are identified. Using the resonance, intercombination and forbidden lines of the few prominent helium-like ions, we infer a density greater than 2 x 10(12) cm(-3) and a temperature of similar to 2 MK for the oxygen and neon line emitting regions in the accretion column of AM Her.
