Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

Detailed characterization of an extrasolar planet's atmosphere provides the best hope for
distinguishing the makeup of its outer layers, and the only hope for understanding the …

Thousands of exoplanets have now been discovered with a huge range of masses, sizes
and orbits: from rocky Earth-like planets to large gas giants grazing the surface of their host …

Exoplanets orbiting close to their parent stars may lose some fraction of their atmospheres
because of the extreme irradiation,,,,,. Atmospheric mass loss primarily affects low-mass …

PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing
accurate key planet parameters (radius, mass, density and age) in statistical numbers, it …

Extremely irradiated hot Jupiters, exoplanets reaching dayside temperatures> 2000 K,
stretch our understanding of planetary atmospheres and the models we use to interpret …

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 …

We use models of coupled thermal evolution and photo-evaporative mass loss to
understand the formation and evolution of the Kepler-36 system. We show that the large …

We present three transit observations of HD 189733 b obtained with the high-resolution
spectrograph CARMENES at Calar Alto. A strong absorption signal is detected in the near …

Observational evidence for escaping exoplanet atmospheres has been obtained for a few
exoplanets to date. It comes from strong transit signals detected in the ultraviolet, most …
