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 …

Mass and radius are two of the most fundamental properties of an astronomical object.
Increasingly, new planet discoveries are being announced with a measurement of one of …

We carried out a Bayesian homogeneous determination of the orbital parameters of 231
transiting giant planets (TGPs) that are alone or have distant companions; we employed …

We provide a database of transit times and updated ephemerides for 382 planets based on
data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported …

Abstract Upcoming James Webb Space Telescope observations will allow us to study
exoplanet and brown dwarf atmospheres in great detail. The physical interpretation of these …

The ExoClock project is an inclusive, integrated, and interactive platform that was developed
to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project …

We present a grid of forward model transmission spectra, adopting an isothermal
temperature-pressure profile, alongside corresponding equilibrium chemical abundances …

We present the discovery and validation of two TESS exoplanets orbiting nearby M dwarfs:
TOI-2084 b, and TOI-4184b. We characterized the host stars by combining spectra from …

The number of exoplanets discovered already exceeds 5000 and continues to increase
daily. The characterization of exoplanets will be the main goal of future space missions. The …

The Ariel mission will observe spectroscopically around 1000 exoplanets to further
characterise their atmospheres. For the mission to be as efficient as possible, a good …
