Based on new observations and improved modeling techniques, we have re-analyzed seven Cepheids in the Large Magellanic Cloud.
LMC distance determined with the accuracy of 2% using binary systems composed of giants.
First determination of the projection factor from the analysis of a eclipsing binary system OGLE-LMC-CEP-0227.
Very precise mass determination of the Cepheid OGLE-LMC-CEP-1812 in an eclipsing binary system.
