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…
