Coulomb plasmas in outer envelopes of neutron stars
A. Y. Potekhin, G. Chabrier, D. G. Yakovlev
Outer envelopes of neutron stars consist mostly of fully ionized, strongly coupled Coulomb plasmas characterized by typical densities about 10^4-10^{11} g/cc and temperatures about…
Towards a consistent model of the Galaxy: I. kinematic properties, star counts and microlensing observations
D. Méra, G. Chabrier, R. Schaeffer
We examine the most recent observational constraints arising from i) small-scale and large-scale Galactic dynamical properties, ii) star counts at faint magnitude and iii) microlen…
Towards a consistent model of the Galaxy: II. Derivation of the model
D. Méra, G. Chabrier, R. Schaeffer
We use the calculations derived in a previous paper (Méra, Chabrier and Schaeffer, 1997), based on observational constraints arising from star counts, microlensing experiments and…
The morphological segregation of galaxies in clusters. III. The distant cluster Cl0939+4713 (Abell 851)
S. Andreon, E. Davoust, T. Heim
We have performed an isophotal analysis of galaxies in the distant (z=0.4) cluster Cl0939+4713 (Abell 851), using post-refurbished Hubble Space Telescope images. Morphological type…
