Peering into the formation history of beta Pictoris b with VLTI/GRAVITY long baseline interferometry
GRAVITY Collaboration, M. Nowak, S. Lacour +65
Our objective is to estimate the C/O ratio in the atmosphere of beta Pictoris b and obtain an estimate of the dynamical mass of the planet, as well as to refine its orbital paramet…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
MIRACLES: atmospheric characterization of directly imaged planets and substellar companions at 4-5 m. I. Photometric analysis of Pic b, HIP 65426 b, PZ Tel B and HD 206893 B
Tomas Stolker, Sascha P. Quanz, Kamen O. Todorov +6
Directly imaged planets and substellar companions are key targets for the characterization of self-luminous atmospheres. Their photometric appearance at 4-5 m is sensitive to th…
Ionized calcium in the atmospheres of two ultra-hot exoplanets WASP-33b and KELT-9b
F. Yan, N. Casasayas-Barris, K. Molaverdikhani +25
Ultra-hot Jupiters are emerging as a new class of exoplanets. Studying their chemical compositions and temperature structures will improve the understanding of their mass loss rate…
From cold to hot irradiated gaseous exoplanets: Fingerprints of chemical disequilibrium in atmospheric spectra
Karan Molaverdikhani, Thomas Henning, Paul Mollière
Almost all planetary atmospheres are affected by disequilibrium chemical processes. In this paper we introduce our recently developed Chemical Kinetic Model (\texttt{ChemKM}). We s…
Search for gas from the disintegrating rocky exoplanet K2-22b
A. R. Ridden-Harper, I. A. G. Snellen, C. U. Keller +1
[Abridged] Aims. We searched for circumplanetary sodium and ionized calcium gas around the disintegrating rocky exoplanet K2-22 b to constrain its gas-loss and sublimation processe…
