O-C diagrams and period changes in stellar systems
Original language description
Based on the visual inspection of all O-C diagrams available in the O-C gateway managed by the Variable stars and exoplanet section of the Czech astronomical society we present an overview of possible shapes of O-C diagrams together with discussion of possible effects causing such dependences. The nature of these effects is discussed for various types of periodic variable. We also give short remarks on interesting eclipsing systems BV Dra and BW Dra which form a visual pair and show antiparallel changesof their O-C diagrams. In addition we comment on period changes of UU Cam, and argue that it probably shows long-term Light Time Effect (LiTE) rather than sudden period change. Effects which are observable only in ultra-precise, quasi-continual measurements gathered by the Kepler satellite are discussed at the end of this contribution.
