Determination of the LMC distance modulus from the Classical Cepheid   Period-Luminosity relation
  The distance modulus of the Large Magellanic Cloud (LMC) is the first step on the determination of the cosmic distance scale. In this paper it is obtained from a new calibration of the classical Cepheid Period-Luminosity (PL) relation. Our new calibration is obtained by applying the LM method -- a parametric method designed to obtain luminosity calibrations from astrometric information -- to the Hipparcos data for Classical Cepheids. The resulting distance modulus is $18.35^{m}\pm 0.13$.
