Moreau,F. Tajhmady +32 more
TL;DR: In this article, the period-luminosity relation of classical Cepheids in samples of different metallicity was investigated and a zero-point offset between SMC and LMC was found, which amounts to a difference between inferred and true distance modulus.

TL;DR: In this article, the period-Luminosity relation of 481 Cepheids with 3 millions two colour measurements in the Large Magellanic Cloud and the Small Magelli Cloud obtained as a by-product of the EROS microlensing survey was studied.

TL;DR: Candidate pre-main-sequence stars observed in the bar of the Large Magellanic Cloud during the search for dark matter in the galactic halo had irregular photometric variations and hydrogen emission lines in their optical spectra, which suggested that these stars are pre- main-sequenceStars of about 10 solar masses.
