We present the discovery and characterisation of two transiting planets observed by the
Transiting Exoplanet Survey Satellite (TESS) orbiting the nearby (d⋆≈ 22 pc), bright (J≈ 9 …

The CARMENES instrument consists of two cross-dispersed´ echelle spectrographs, which
together cover the wavelength range from 5,200 to 17,100˚ A. During its first five years of …

Past studies have demonstrated that atmospheric escape by the core-powered mass-loss
mechanism can explain a multitude of observations associated with the radius valley that …

Multiplanet systems are valuable arenas for investigating exoplanet architectures and
comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K dwarf …

A systematic, population-level discrepancy exists between the densities of exoplanets
whose masses have been measured with transit timing variations (TTVs) versus those …

Context. The leading spectrographs used for exoplanets' search and characterization offer
online data reduction softwares (DRS) that yield, as an ancillary result, the full-width at half …

Context. Most of the currently known planets are small worlds with radii between that of the
Earth and that of Neptune. The characterization of planets in this regime shows a large …

Atmospheric mass-loss is known to play a leading role in sculpting the demographics of
small, close-in exoplanets. Knowledge of how such planets evolve allows one to 'rewind the …

Context. Despite being a prominent subset of the exoplanet population discovered in the
past three decades, the nature and provenance of sub-Neptune-sized planets is still one of …

The connection between outer gas giants and inner super-Earths reflects their formation and
evolutionary histories. Past work exploring this link has suggested a tentative positive …
