We're hiring

Join the Araucaria Project! We are looking for a postdoc fellow with an observational background, who is eager to work on pulsating stars and eclipsing binaries at Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences in Warsaw, Poland. Apply till the end of April and join us as soon as September or as late as December 2021 (PhD diploma is not required at the stage of application, but is mandatory at the stage of signing job contract). For more information click here and here.

The main goal of the Araucaria Project is to improve the calibration of the cosmic distance scale in the local Universe. We are tracing down the environmental dependencies of the various standard candles by comparing their distances obtained with different methods.

Our recent results:

  • The surface brightness-colour relations based on eclipsing binary stars and calibrated with Gaia EDR3 — paper
  • A numerous population of double-lined binary Cepheids — paper
  • Metallicities and ages for 35 star clusters and their surrounding fields in the Small Magellanic Cloud — paper
  • Deep near-infrared photometric maps of Carina, Fornax, and Sculptor — paper — photometric maps
  • Empirical calibration of the reddening maps in the Magellanic Cloudspaperextinction maps
  • Period-luminosity relation for classical Cepheids in the Milky Way from Gaia parallaxes — paper
  • Surface brightness-color relation calibrated with interferometry — paper
  • Spectral analysis and stellar parameters of detached O-type systems — paper I, paper II
