Symbiotic stars are long-period interacting binaries where the compact objects, most commonly a white dwarf, is embedded in dense stellar wind of an evolved companion star. UV and soft X-ray emission accretion disk nuclear burning dwarf plays major role shaping ionisation balance surrounding material giving rise to rich line emission. In this paper, we employ 2D photoionisation calculations bas...

Abstract We studied the electronic structure of lithium metal, fluoride, and spodumene using density functional theory. performed calculations total, local partial states, x‐ray emission spectra. observed changes in Li K spectra shape energy position due to chemical composition modification. also outline possible interferences between bands.
