The origin of star formation since z=1

F. Hammer, M. Puech, Y. B. Yang +1

The use of multiple integral field units with FLAMES/GIRAFFE at VLT has revolutionized investigations of distant galaxy kinematics. This facility may recover the velocity fields of…

Non-LTE Analysis of Lyman-Line Observations of a Filament with SUMER

P. Schwartz, B. Schmieder, P. Heinzel

We present non-LTE diagnostics of the filament observed by SOHO/SUMER on May 27, 2005 in the whole Lyman series. The filament was situated close to the disk center. The Ly_alpha ob…

X-ray powerful diagnostics for highly-ionized plasmas: He-like ions

D. Porquet, R. Mewe, J. S. Kaastra +2

The calculations of the ratios of the Helium-like ion X-ray lines from C V to Si XIII are revisited in order to apply the results to density, temperature and ionization process dia…

Oscillation power across the HR diagram : sensitivity to the convection treatment

Reza Samadi, Guenter Houdek, Marie-Jo Goupil +2

Solar-like oscillations are stochastically excited by turbulent convection. In this work we investigate changes in the acoustic oscillation power spectrum of solar-type stars by va…

Rapidly rotating strange stars

D. Gondek-Rosinska, P. Haensel, J. L. Zdunik +1

We study effects of the strange quark mass and of the QCD coupling constant in the MIT bag model of quark matter with lowest order quark-gluon interactions on the rapid rotation of…

The Auto-Correlation Function of the extragalactic background light: I. Measuring gravitational shear

L. Van Waerbeke, Y. Mellier, P. Schneider +2

A new method for measuring the shear induced by gravitational light deflection is proposed. It is based on analyzing the anisotropy induced in the auto-correlation function (ACF) o…
