A catalogue of 541 nearby (within 10pc of the sun) stars, brown dwarfs, and confirmed exoplanets in 336 systems, as well 21 candidates, compiled from SIMBAD and several other...

The LIFE Target Star Database contains information useful for the planned LIFE mission_ (mid-ir, nulling interferometer in space). It characterizes possible target systems...

The Kepler satellite has observed the Galactic center in a campaign lasting from April until the end of June 2016 (K2/C9). The main objective of the 99 hours for the...

The LIFE Target Star Database contains information useful for the planned LIFE mission_ (mid-ir, nulling interferometer in space). It characterizes possible target systems...

The formation and evolution of ultra-short-period (USP) rocky planets is poorly understood. However, it is widely thought that these planets could not have formed at their...

We have conducted a planetary radial velocity measurement of the ultrahot Jupiter WASP-121b using JWST NIRSpec phase curve data. Our analysis reveals the Doppler shift of the...

We present Super-RDI, a unique framework for the application of reference star differential imaging (RDI) to Keck/NIRC2 high-contrast imaging observations with the vortex...

Previous studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and magnetic...

Ultra-hot Jupiters are gas giant exoplanets strongly irradiated by their star, which sets intense molecular dissociation leading to atmospheric chemistry dominated by ions and...

Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an...

We constrain the sky-projected obliquities of two low-density hot Neptune planets, HATS-38 b and WASP-139 b, orbiting nearby G and K stars using Rossiter-McLaughlin (RM)...

Using high-precision photometry, NASA's TESS space mission has discovered many intriguing transiting planet candidates. These discoveries require ground-based follow-up...

Complete, accurate, and precise catalogues of exoplanet host star (EHS) properties are essential to derive high-quality exoplanet parameters, and, thus, to study individual...

We present the discovery of TOI 762 A b and TIC 46432937 b, two giant planets transiting M-dwarf stars. Transits of both systems were first detected from observations by the...

The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric studies can now put...

With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains...

Periodic radial velocity variations in the nearby M-dwarf star Gl 411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to...

Comparing the properties of planets orbiting the same host star, and thus formed from the same accretion disc, helps in constraining theories of exoplanet formation and...

Due to observational biases, a large fraction of known exoplanets are short-period objects. However, the search for planets began more than 20 years ago, so it is already...

We intended to quantify the impact of stellar multiplicity on the presence and properties of exoplanets. We investigated all exoplanet host stars at less than 100 pc using the...
