Titanium oxide and chemical inhomogeneity in the atmosphere of the exoplanet WASP-189b
Bibiana Prinoth, H. Jens Hoeijmakers, Daniel Kitzmann +21
The temperature of an atmosphere decreases with increasing altitude, unless a shortwave absorber exists that causes a temperature inversion. Ozone plays this role in the Earth`s at…
Physically-motivated basis functions for temperature maps of exoplanets
Brett M. Morris, Kevin Heng, Kathryn Jones +4
Thermal phase curves of exoplanet atmospheres have revealed temperature maps as a function of planetary longitude, often by sinusoidal decomposition of the phase curve. We construc…
Into the Storm: Diving into the winds of the ultra hot Jupiter WASP-76 b with HARPS and ESPRESSO
J. V. Seidel, D. Ehrenreich, A. Allart +26
Despite swift progress in the characterisation of exoplanet atmospheres in composition and structure, the study of atmospheric dynamics has not progressed at the same speed. While…
The 13O-rich atmosphere of a young accreting super-Jupiter
Yapeng Zhang, Ignas Snellen, Alexander J. Bohn +8
Isotope abundance ratios play an important role in astronomy and planetary sciences, providing insights in the origin and evolution of the Solar System, interstellar chemistry, and…
Molecular mapping of the PDS70 system: No molecular absorption signatures from the forming planet PDS70 b
G. Cugno, P. Patapis, T. Stolker +7
Aims. We aim to detect molecules in the atmosphere of the young forming companion PDS70 b by searching for atmospheric absorption features typical of substellar objects. Methods. W…
Biosignatures of the Earth I. Airborne spectropolarimetric detection of photosynthetic life
C. H. Lucas Patty, Jonas G. Kühn, Petar H. Lambrev +10
Context. Homochirality is a generic and unique property of life on Earth and is considered a universal and agnostic biosignature. Homochirality induces fractional circular polariza…
A Spectral Survey of WASP-19b with ESPRESSO
Elyar Sedaghati, Ryan J. MacDonald, Núria Casasayas-Barris +10
High resolution precision spectroscopy provides a multitude of robust techniques for probing exoplanetary atmospheres. We present multiple VLT/ESPRESSO transit observations of the…
HELIOS-K 2.0 Opacity Calculator and Open-source Opacity Database for Exoplanetary Atmospheres
Simon L. Grimm, Matej Malik, Daniel Kitzmann +12
Computing and using opacities is a key part of modeling and interpreting data of exoplanetary atmospheres. Since the underlying spectroscopic line lists are constantly expanding an…
