| Description
| - Eclipsing binaries (hereafter EBs) are excellent laboratories for studying a wide variety of processes in stellar astrophysics. The main scientific aim of this project is photometric study of selected eclipsing binaries. The project is focused on two groups of EBs: 1. Faint neglected eclipsing variable stars (about 15 mag in minimum of brightness). These stars have been very often observed only by discoverer many decades ago. 2. Very bright (< 8 mag) and brand-new eclipsing binaries (discovered by Hipparcos, ASAS and other), for which new photometric observations are missing. Observations should be made as at least two-colour CCD photometry. For chosen stars we obtain new, more correct information about their light curves. We can compute models ofthese binary systems using standard Wilson-Devinney model as well as new methods developed later by other authors (FOTEL, Nightfall). Light curves and models of chosen stars have not been published yet. (en)
- Studium zákrytových dvojhvězd umožňuje výzkum širokého spektra procesů ve hvězdné astrofyzice. Hlavním vědeckým cílem tohoto projektu je fotometrický výzkum vybraných zákrytových dvojhvězd. Projekt je zaměřen na dvě skupiny dvojhvězd: 1. Slabé a opomíjené zákrytové proměnné hvězdy (kolem 15 mag v minimu jasnosti). Tyto hvězdy byly často sledovány pouze objeviteli před několika desítkami let. 2. Velmi jasné (< 8 mag) a nedávno objevené zákrytové dvojhvězdy (Hipparcos, ASAS, aj.), pro něž chybí nová přesná fotometrická měření. Pozorování by měla být prováděna jako alespoň dvoubarevná CCD fotometrie. Pro zvolené soustavy tak získáme nové, případně přesnější informace o jejich světelných křivkách. To nám umožní řešit příslušné modely systémů užitím standardního Wilsonova-Devinneyho modelu případně pomocí nových metod vyvinutých později (FOTEL, Nightfall). Světelné křivky i modely nebyly dosud pro zvolené soustavy publikovány.
