In the coming years and decades, advanced space-and ground-based observatories will
allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially …

At the dawn of the first discovery of exoplanets orbiting Sun-like stars in the mid-1990s, few
believed that observations of exoplanet atmospheres would ever be possible. After the 2002 …

Chemical disequilibrium in planetary atmospheres has been proposed as a generalized
method for detecting life on exoplanets through remote spectroscopy. Among solar system …

In the search for life on Earth-like planets around other stars, the first (and likely only)
information will come from the spectroscopic characterization of the planet's atmosphere. Of …

Context. Optical interferometry is at a key development stage. The Very Large Telescope
Interferometer (VLTI) has established a stable, robust infrastructure for long-baseline …

Exoplanet observations promise one day to unveil the presence of extraterrestrial life.
Atmospheric compounds in strong chemical disequilibrium would point to large-scale …

We present an efficient method for probing the orbital angular momentum of optical vortices
of arbitrary sizes. This method, based on a multipoint interferometer, has its most important …

Context. Temperate terrestrial exoplanets are likely to be common objects, but their
discovery and characterization is very challenging because of the small intrinsic signal …

Context. Since low-mass stars have low luminosities, orbits at which liquid water can exist
on Earth-sized planets are relatively close-in, which produces Doppler signals that are …

Tremendous progress in the science of extrasolar planets has been achieved since the
discovery of a Jupiter orbiting the nearby Sun-like star 51 Pegasi in 1995. Theoretical …
