Grid turbulence in dilute polymer solutions: PEO in water

Grid turbulence of polyethylene oxide (PEO) solutions (Polyox WSR-301 in H2O) has been investigated experimentally for three concentrations of 25, 50 and 100 weight ppm, at a turbulence Reynolds number based on a Taylor microscale of Re-lambda approximate ...

Nucleosynthesis And The Inhomogeneous Chemical Evolution Of The Carina Dwarf Galaxy

Pascale Jablonka

The detailed abundances of 23 chemical elements in nine bright red giant branch stars in the Carina dwarf spheroidal galaxy are presented based on high-resolution spectra gathered at the Very Large Telescope (VLT) and Magellan telescopes. A spherical model ...

A Multi-Site Campaign To Measure Solar-Like Oscillations In Procyon. Ii. Mode Frequencies

We have analyzed data from a multi-site campaign to observe oscillations in the F5 star Procyon. The data consist of high-precision velocities that we obtained over more than three weeks with 11 telescopes. A new method for adjusting the data weights allow ...

The NIR Ca II triplet at low metallicity Searching for extremely low-metallicity stars in classical dwarf galaxies

Pascale Jablonka, Martin Tafelmeyer

The NIR Ca II triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group, providing a better understanding of metallicities of stars in the Milky Way and dwarf galaxies ...

The fundamental plane of EDisCS galaxies The effect of size evolution

Pascale Jablonka

We study the evolution of spectral early-type galaxies in clusters, groups, and the field up to redshift 0.9 using the ESO Distant Cluster Survey (EDisCS) dataset. We measure structural parameters (circularized half-luminosity radii R-e, surface brightness ...

The dynamical and chemical evolution of dwarf spheroidal galaxies

Pascale Jablonka, Yves Revaz

We present a large sample of fully self-consistent hydrodynamical Nbody/Tree-SPH simulations of isolated dwarf spheroidal galaxies (dSphs). It has enabled us to identify the key physical parameters and mechanisms at the origin of the observed variety in th ...

Experimental investigation into localized instabilities of mixed Rayleigh-Bénard-Poiseuille convection

Emeric Grandjean

An experimental study of the stability of the Rayleigh-Bénard-Poiseuille flow was performed in a large transverse aspect ratio channel. The onset for the transverse thermo-convective rolls was determined as a function of the Reynolds number for two differe ...

The evolution of the brightest cluster galaxies since z similar to 1 from the ESO Distant Cluster Survey (EDisCS)

Pascale Jablonka, Anja Von der Linden

We present K-band data for the brightest cluster galaxies (BCGs) from the ESO Distant Cluster Survey (EDisCS). These data are combined with the photometry published by Aragon Salamanca, Baugh & Kauffmann and a low-redshift comparison sample built from the ...
