Extragalactic eclipsing binaries open a new perspective on the study of stellar structure and evolution. Stars in different galaxies have formed and evolved in environments with chemical histories that may differ from those of the solar neighborhood. For example, the LMC and SMC contain low-metallicity, young massive stars that are no longer found in our Galaxy. Eclipsing binaries, yielding accurate...
Eclipsing binaries, both inside and outside our Galaxy, are proving to be powerful tools for studying a wide spectrum of astrophysical problems. They are also are extremely valuable for providing fundamental quantities such as stellar masses, radii, luminosities, ages and distances. Recently, eclipsing binaries are turning out to be accurate distance indicators for star clusters inside our Galaxy...
