Welcome to var.astro.cz, an internet portal of Czech variable star researchers!

Variable Star and Exoplanet Section of Czech Astronomical Society was found in 1924 (as Variable Star Section of CAS). Since the time, it's an organisation coordinating research and observing of variable stars (and exoplanets in last years) in Czech republic (member of EU). Members of our Section are mostly advanced amateur and professional astronomers.

Main observing and research activities are collected in 4 projects:

  • Project B.R.N.O. - observing and research of eclipsing binaries
  • Project MEDUZA - observing and research of intrinsic variables (mostly pulsating stars)
  • Project TRESCA - observing transits of known exoplanetary systems, searching for new exoplanets in known transiting systems and searching for new transiting exoplanetary systems.
  • Project HERO - observing and research of high energy sources in cooperation with High-energy research group from Ondrejov (cataclysmic variables, quasars, blazars, x-rays, gamma-rays).
