The LMC distance modulus from Hipparcos RR Lyrae and classical Cepheid data

open access: yes, 1998
. The LM method (Luri, Mennessier et al., 1996), designed to exploit the Hipparcos data to obtain luminosity calibrations, is applied to derive luminosity calibrations for RR Lyrae and classical Cepheids. From these calibrations the distance to the Large

A direct distance to the Large Magellanic Cloud Cepheid HV 12198 from the infrared surface brightness technique

open access: yes, 2000
We report on the first application of the infrared surface brightness technique on a Cepheid in the Large Magellanic Cloud, the variable HV 12198 in the young globular cluster NGC 1866.

A Cepheid distance to the Fornax cluster and the local expansion rate of the Universe

open access: yes, 1998
Both galaxy distances and velocities are required for the determination of the expansion rate of the Universe, as described by the Hubble constant H_0. The radial velocities of galaxies arise not just from this expansion but also from random components ...
