Abstract

Studies of abundances of elements in X-ray emitting plasmas of stars are important as these can help us to understand the chemistry of stars and their interiors, dispersal of the elements in the supernova explosions and enrichment of interstellar medium, the evolution of galaxies, and the impact on the compositions of planets around young stars. Here, I review some recent results of studies of elemental abundances of X-ray emitting plasmas in the corona of cool stars similar to the Sun, pre-main sequence low-mass stars, and early-type stars. I discuss the current status of abundance patterns observed in stellar X-ray plasmas, using plasma diagnostics accessible via high resolution X-ray spectroscopy with Chandra and XMM-Newton.
