چکیده
Darwin is one of the most challenging space projects ever considered by the European Space Agency ESA Its principal objectives are to detect Earth like planets around nearby stars and to characterise their atmospheres Within the frame of the Darwin programme the European Space Agency ESA and the European Southern Observatory ESO intend to build a ground based technology demonstrator Such a ground based demonstrator built around the Very Large Telescope Interferometer VLTI in Paranal will test some of the key technologies required for the Darwin Infrared Space Interferometer The present paper will describe the objectives and the status of the project

The Darwin Ground-based European Nulling Interferometry Experiment (GENIE)
Darwin is one of the most challenging space projects ever considered by the European Space Agency (ESA). Its principal objectives are to detect Earth-like planets around nearby stars and to characterise their atmospheres. Darwin is conceived as a space \nulling interferometer" which makes use of on-axis destructive interferences to extinguish the stellar light while keeping the o -axis signal o...
متن کاملPerformance study of ground-based infrared Bracewell interferometers Application to the detection of exozodiacal dust disks with GENIE
Nulling interferometry, a powerful technique for high-resolution imaging of the close neighbourhood of bright astrophysical objets, is currently considered for future space missions such as Darwin or the Terrestrial Planet Finder Interferometer (TPF-I), both aiming at Earth-like planet detection and characterization. Ground-based nulling interferometers are being studied for both technology dem...
متن کاملNulling interferometry: performance comparison between Antarctica and other ground-based sites
Context. Detecting the presence of circumstellar dust around nearby solar-type main sequence stars is an important pre-requisite for the design of future life-finding space missions such as ESA’s Darwin or NASA’s Terrestrial Planet Finder (TPF). The high Antarctic plateau may provide appropriate conditions to perform such a survey from the ground. Aims. We investigate the performance of a nulli...
متن کاملAladdin Nulling Instrument
The ALADDIN project aims at detecting warm dust populations around nearby main sequence stars. In order to achieve the significantly improved sensitivity with respect to existing instruments, the architecture of the system is focused and optimised for the mission: ALADDIN implements the nulling interferometry technique at the focal plane of a 2-telescope interferometer mounted on a rotating str...
متن کاملNulling interferometry: performance comparison between space and ground-based sites for exozodiacal disc detection
Context. Characterising the circumstellar dust around nearby main sequence stars is a necessary step in understanding the planetary formation process and is crucial for future life-finding space missions such as ESA’s Darwin or NASA’s Terrestrial Planet Finder (TPF). Besides paving the technological way to Darwin/TPF, the space-based infrared interferometers Pegase and FKSI (FourierKelvin Stell...
