A Numerical Simulator for VITRUV
VITRUVsim is a numerical tool with as much as possible physics included. Inputs are the source parameters (flux, morphology, position...) and outputs are sequences of observed fringes and/or reduced visibilities....

GENIE: a Ground-Based European Nulling Instrument at ESO Very Large Telescope Interferometer
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, to analyze the compositio...

Milli-arcsecond Astrophysics with VSI, the VLTI Spectro-imager in the ELT Era
Nowadays, compact sources relatively warm like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei can be investi...

MATISSE
MATISSE is foreseen as a mid-infrared spectro-interferometer combining the beams of up to four UTs/ATs of the Very Large Telescope Interferometer (VLTI). MATISSE will measure closure phase relations and thus o...

Prospects for Near-infrared Characterisation of Hot Jupiters with the VLTI Spectro-imager (VSI)
Since the discovery of the first exoplanet around 51 Pegasi, the study of planetary systems receives an increasing attention, with the development and test of more and more detection techniques. Among the dire...

Open AccessDarwin—an experimental astronomy mission to search for extrasolar planets
As a response to ESA call for mission concepts for its Cosmic Vision 2015–2025 plan, we propose a mission called Darwin. Its primary goal is the study of terrestrial extrasolar planets and the search for life on ...

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...

Prospects for the characterisation of exo-zodiacal dust with the VLTI
Exo-zodiacal dust, exozodi for short, is warm (∼300 K) or hot (up to ∼2000 K) dust found in the inner regions of planetary systems around main sequence stars. In analogy to our own zodiacal dust, it may be loc...

The path towards high-contrast imaging with the VLTI: the Hi-5 project
The development of high-contrast capabilities has long been recognized as one of the top priorities for the VLTI. As of today, the VLTI routinely achieves contrasts of a few 10− 3 in the near-infrared with PIONIE...

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 ...

Open AccessImaging low-mass planets within the habitable zone of α Centauri
Giant exoplanets on wide orbits have been directly imaged around young stars. If the thermal background in the mid-infrared can be mitigated, then exoplanets with lower masses can also be imaged. Here we prese...

A rich hydrocarbon chemistry and high C to O ratio in the inner disk around a very low-mass star
Carbon is an essential element for life but how much can be delivered to young planets is still an open question. The chemical characterization of planet-forming disks is a crucial step in our understanding of...

Open AccessWater in the terrestrial planet-forming zone of the PDS 70 disk
Terrestrial and sub-Neptune planets are expected to form in the inner (less than 10 au) regions of protoplanetary disks1. Water plays a key role in their formation2–4, although it is yet unclear whether water mol...
