Abstract
TW Draconis is one of the best studied Algol-type eclipsing binaries. There is significant evidence for miscellaneous interacting physical processes between binary components and these are manifested in period and light curve changes. We studied these processes on the basis of a long-time series of photometric and spectroscopic observations.
Abstract (in Czech)
TW Draconis je jednou z nejlépe studovaných zákrytových dvojhvězd typu Algol. Existují hodnověrné důkazy pro různorodé interakční fyzikální procesy mezi složkami dvojhvězdy, jež se vyjevují změnami světelné křivky a orbitální periody. Studovali jsme je na základě dlouhodobých řad fotometrických a spektroskopických pozorování.
