Optical Linear Polarimetry of Ultra Cool Dwarfs

Francois Menard, Xavier Delfosse, Jean-Louis Monin

Optical linear polarimetry of 8 ultra cool field dwarfs, with spectral types ranging from M9 to L8, is presented. The linear polarisation, P, of each dwarf we measured is P < 0.2%.…

Supersymmetric Analysis of a Simplified Two Dimensional Anderson Model at Small Disorder

J. Bellissard, J. Magnen, V. Rivasseau

This work proposes a very simple random matrix model, the Flip Matrix Model, liable to approximate the behavior of a two dimensional electron in a weak random potential. Its constr…

More concerning the anelastic and subseismic approximations for low-frequency modes in stars

M. Rieutord, B. Dintrans

Two approximations, namely the subseismic approximation and the anelastic approximation, are presently used to filter out the acoustic modes when computing low frequency modes of a…

The vertical structure of T Tauri accretion discs III. Consistent interpretation of spectra and visibilities with a two-layer model

Regis Lachaume, Fabien Malbet, Jean-Louis Monin

We present a two-layer accretion disc model developed to simultaneously fit optical long baseline visibilities and spectral energy distributions of T Tauri accretion discs. Our mod…

Macroscopic Anisotropy and Symmetry Breaking in the Pyrochlore Antiferromagnet GdTiO}

A. K. Hassan, L. P. Lévy, C. Darie +1

In the Heisenberg antiferromagnet , the exchange interactions are geometrically frustrated by the pyrochlore lattice structure. This ESR study reveals a strong tempera…

Adiabatic oscillations of non-rotating superfluid neutron stars

Reinhard Prix, Michel Rieutord

We present results concerning the linear (radial and non-radial) oscillations of non-rotating superfluid neutron stars in Newtonian physics. We use a simple two-fluid model to desc…
