Collisions of emitters and absorbers with charged particles influence on the spectral line profiles of stellar plasma, due to splitting and shifting of atomic energy levels in electric field (Stark effect) resulting in broadening and shift of spectral lines. Here is analyzed the importance of Stark broadening for analyzis, interpretation and synthesis of stellar spectra, and analyzis, diagnostics and modeling of stellar plasma, and discussed the significance of such results in other research fields. It was considered for which types of stars and for which investigations Stark broadening is significant and methods for theoretical determination of Stark broadening parameters are discussed. Such investigations on Belgrade Astronomical Observatory are reviewed as well.
