Space-based infrared interferometry to study exoplanetary atmospheres
The quest for other habitable worlds and the search for life among them are major goals of modern astronomy. One way to make progress towards these goals is to obtain high-quality spectra of a large number of ...

A transiting giant planet with a temperature between 250 K and 430 K
About 70 of the more than 400 known extrasolar planets transit their central star, making it possible to observe their atmospheres and determine various key parameters. The transiting extra-solar planets so fa...

PEGASE, an infrared interferometer to study stellar environments and low mass companions around nearby stars
PEGASE is a mission dedicated to the exploration of the environment (including habitable zone) of young and solar-type stars (particularly those in the DARWIN catalogue) and the observation of low mass compani...

Dynamics of elastic bodies connected by a thin adhesive layer
We study a problem of wave propagation in a structure made of two tridimensional elastic bodies connected by a thin adhesive layer. We recall that, after several heuristic models, the bonding problem, which ba...

Stability of discrete systems involving shocks and friction
The stability of the equilibrium states of a simple mechanical system with unilateral contact and Coulomb friction is explored. When the external force is constant, the equilibrium states are completely determ...

Strategies for Remote Detection of Life
The history of Astronomy has taught us not to be anthropocentric. When searching for extrasolar lives, we have to keep in mind this lesson, not trying to search for our twins. Specifically, we should base our ...

The Darwin Project
Angel and co-workers have proposed to detect exoplanets around nearby stars in the infrared (6–17 μm) and to analyze their spectra, searching for H2O, CO2, CH4, NH3, and O3 spectral features. The presence or abse...

How to Search for Extra-Solar Planets with the VLT/VISA?
We review the motivation for searching for Extra-Solar planets, and point out that we really do not know if the Solar System is a common place or a rare stellar system. A weak version of the Anthropic Principle p...

Carrier of the Emission λ5797 DIB in the Red Rectangle: Suprathermally Rotating PAH?
Assuming that free PAHs are the carriers of the λ5797 DIB observed in emission in the Red Rectangle, we investigate the physics of the rotation of such a molecule in order to interpret: i) a band structure indica...
