Exoplanetary science is on the verge of an unprecedented revolution. The thousands of
exoplanets discovered over the past decade have most recently been supplemented by …

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 a distance of 1.295 parsecs, the red dwarf Proxima Centauri (α Centauri C, GL 551, HIP
70890 or simply Proxima) is the Sun's closest stellar neighbour and one of the best-studied …

This paper presents an overview of SPIRou, the new-generation near-infrared
spectropolarimeter/precision velocimeter recently installed on the 3.6-m Canada–France …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

We describe how environmental context can help determine whether oxygen (O2) detected
in extrasolar planetary observations is more likely to have a biological source. Here we …

The detection of satellites around extrasolar planets, so called exomoons, remains a largely
unexplored territory. In this work, we study the potential of detecting these elusive objects …

Radial velocity monitoring has found the signature of a Msini= 1.3M⊕ planet located within
the habitable zone (HZ) of Proxima Centauri. Despite a hotter past and an active host star …

Context. Atmospheric properties of exoplanets can be constrained with transit spectroscopy.
At low spectral resolution, this technique is limited by the presence of clouds. The signature …
