Course objectives (in Czech)
Předmět je určen studentům odborné fyziky se zaměřením na astrofyziku. V přednášce je podáváno hlubší seznámení s současnou astrofyzikální teorií přenosu záření, s problematikou fyzikálních podmínek v atmosférách hvězd a se vznikem spojitého a čárového spektra. Rozebírány jsou jednotlivé rozšiřovací mechanismy u spektrálních čar.
