We use PyDynamicaLC, a model using the least number of--and the least correlated--degrees of freedom needed to derive a photodynamical model, to describe some of the...

Planetary radii are derived for 218 exoplanets orbiting 161 M dwarf stars. Stellar radii are based on an analysis of APOGEE high-resolution near-IR spectra for a subsample of...

WASP-121 b has been established as a benchmark ultrahot Jupiter, serving as a laboratory for the atmospheric chemistry and dynamics of strongly irradiated extrasolar gas giants....

We report the confirmation of three transiting exoplanets orbiting TOI-1243 (LSPM J0902+7138), TOI-4529 (G 2-21) and TOI-5388 (Wolf 346) initially detected by TESS, through...

We present the discovery and confirmation of the ultra-short period (USP) planet TOI-2431 b orbiting a nearby (d~36pc) late K star (Teff=4109+/-28K) using observations from the...

Gas giant planets orbiting low-mass stars (Teff<=4600K) are uncommon outcomes of planet formation. Increasing the sample of well-characterised giants around early M dwarfs...

Sub-Neptunes with planetary radii of R_p_=~2-4 R_{Earth} are the most common planets around solar-type stars in short-period (P<100d) orbits. It is still unclear, however,...

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 CARMENES instrument, installed at the 3.5 m telescope of the Calar Alto Observatory in Almería, Spain, was conceived to deliver high-accuracy radial velocity (RV)...

In high-contrast imaging, a novel detection algorithm for angular differential imaging (ADI) sequences has recently been introduced: the Regime Switching Model (RSM). This...

GJ 877 is a bright M dwarf in the solar neighborhood with two currently reported nontransiting exoplanets with periods of 9d and 21d, along with an additional unconfirmed signal...

The transition regime between giant planets (GPs) and brown dwarfs (BDs) is still an open subject of study in exoplanetary science. A complete understanding of the population of...

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...

Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since...

We provide a detailed characterisation of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (M: 0.99M_{sun}_; R: 1.13R_{sun}; age: 7.4Gyr; Vmag: 8.25)...

Like the magnetized planets in our Solar system, magnetized exoplanets should emit strongly at radio wavelengths. Radio emission directly traces the planetary magnetic fields...

We report three new barium (Ba) dwarfs lying in Sirius-like systems. They provide direct evidence that Ba dwarfs are companions to white dwarfs (WDs). Atmospheric parameters,...
