Characterising Extrasolar Planets in Reflected Light and Thermal Emission
Jean Schneider
The physical bases of the detection and characterisation of extrasolar planets in the reflected light and thermal emission regimes are reviewed. They both have their advantages and…
AGN fueling: the observational point of view
F. Combes
Observations at multiple wavelengths are reviewed to search for evidence for fueling mechanisms in galaxies, both for nuclear starbursts and AGN activity. Although it is undisputed…
Seismic diagnostics on stellar convection treatment from oscillation amplitudes of p-modes
R. Samadi, M. J. Goupil, Y. Lebreton +2
The excitation rate P of solar p-modes is computed with a model of stochatic excitation which involves constraints on the averaged properties of the solar turbulence. These constra…
Consequences of the non gaussian character of the stochastic excitation for solar-type oscillations
R. Samadi, A. Nordlund, R. F. Stein +2
Our recent study, based on a 3D numerical simulation, suggested that the stochastic excitation of solar p-modes has a non gaussian nature and a non gaussian model was proposed whic…
Polar ring galaxies: formation and properties
Frederic Bournaud, Francoise Combes
Formation scenarios for polar ring galaxies are studied through N-body simulatio ns that are compared with existing observations. It is shown that polar rings ar e likely to be for…
Molecular gas in the double-barred Seyfert 2 galaxy NGC 5728
F. Combes, S. Leon
We present CO(1-0) and CO(2-1) maps of the Seyfert galaxy NGC 5728. Although a stellar nuclear bar structure is clearly identified in the near-infrared images in the central 10", i…
