AbstractNonlinear convective pulsation models representative of SMC Cepheids pulsating in the second overtone mode are presented. Model predictions are compared with observations and implications are derived for second overtone selection criteria. The role of overtone Cepheids as distance indicators is finally investigated and the derived distance scale is at odds with the so called short distance scale.

Hilbert Type

A Weyl type of action which is scale free and quadratic in the curvature is suggested for strong gravity. The corresponding field equations have solutions which imply confinement. At the QCD scale, the scale invariance is broken inducing a Hilbert type term which describes the short distance behavior. This approach may provide a strong gravity basis for QCD.

Cluster Data

The methods are reviewed that give a distance modulus to the core of the Virgo cluster of m - M = 31.64 ± 0.08 (D = 21.3 ± 0.8 Mpc). It is shown that the cosmic velocity of the cluster core is 1179 ± 17 km s−1, which, when combined with the distance gives Ho= 55 ± 3 km s−1Mpc−1from the Virgo cluster data alone. Nine independent methods are reviewed that confirm that Ho= 50 ± 2. Discussion is made why all methods that are said to give the short distance scale (Ho~ 85) are incorrect.
