Context. KELT-9 b exemplifies a newly emerging class of short-period gaseous exoplanets
that tend to orbit hot, early type stars–termed ultra-hot Jupiters. The severe stellar irradiation …

Giant exoplanets orbiting close to their host stars have high temperatures because of the
immense amount of stellar irradiation that they receive. The extreme energy input leads to …

Ultra-hot Jupiters orbit very close to their host star and consequently receive strong
irradiation, causing their atmospheric chemistry to be different from the common gas giants …

We explore atmospheric escape from close-in exoplanets with the highest mass-loss rates.
First, we locate the transition from stellar X-ray and UV-driven escape to rapid Roche lobe …

We present the discovery and characterization of two transiting planets observed by TESS in
the light curves of the young and bright (V= 9.67) star HD73583 (TOI-560). We perform an …

KELT-9 b, the hottest known exoplanet, with T eq~ 4400 K, is the archetype of a new planet
class known as ultra-hot Jupiters. These exoplanets are presumed to have an atmosphere …

WASP-52b is a low-density hot Jupiter orbiting a moderately active K2V star. Previous low-
resolution studies have revealed a cloudy atmosphere and found atomic Na above the cloud …

Aims. We present a novel method for studying the thermal emission of exoplanets as a
function of orbital phase at very high spectral resolution, and use it to investigate the climate …

We present a spectrally and temporally resolved detection of the optical Mg i triplet at 7.8σ in
the extended atmosphere of the ultra-hot Jupiter KELT-9 b, adding to the list of detected …

We used the HARPS-North high resolution spectrograph (ℛ= 115 000) at Telescopio
Nazionale Galileo (TNG) to observe one transit of the highly irradiated planet MASCARA …
