Three radial gaps in the disk of TW Hydrae imaged with SPHERE

Roy van Boekel, Thomas Henning, Jonathan Menu +24

We present scattered light images of the TW Hya disk performed with SPHERE in PDI mode at 0.63, 0.79, 1.24 and 1.62 micron. We also present H2/H3-band ADI observations. Three disti…

Exploring Biases of Atmospheric Retrievals in Simulated JWST Transmission Spectra of Hot Jupiters

M. Rocchetto, I. P. Waldmann, O. Venot +2

With a scheduled launch in October 2018, the James Webb Space Telescope (JWST) is expected to revolutionise the field of atmospheric characterization of exoplanets. The broad wavel…

The discovery of a planetary candidate around the evolved low-mass Kepler giant star HD 175370

M. Hrudková, A. Hatzes, R. Karjalainen +20

We report on the discovery of a planetary companion candidate with a minimum mass Msini = 4.6 M_J orbiting the K2 III giant star HD 175370 (KIC 007940959). This star was a target i…

Influence of Stellar Flares on the Chemical Composition of Exoplanets and Spectra

Olivia Venot, Marco Rocchetto, Shaun Carl +2

More than 3000 exoplanets have been detected so far, and more and more spectroscopic observations of exoplanets are performed. Future instruments are eagerly awaited as they will b…

The Effects of Consistent Chemical Kinetics Calculations on the Pressure-Temperature Profiles and Emission Spectra of Hot Jupiters

Benjamin Drummond, Pascal Tremblin, Isabelle Baraffe +4

In this work we investigate the impact of calculating non-equilibrium chemical abundances consistently with the temperature structure for the atmospheres of highly-irradiated, clos…

Connecting the dots III: Night side cooling and surface friction affect climates of tidally locked terrestrial planets

L. Carone, R. Keppens, L. Decin

We investigate how night side cooling and surface friction impact surface temperatures and large scale circulation for tidally locked Earth-like planets. For each scenario, we vary…

Cloudless atmospheres for L/T dwarfs and extra-solar giant planets

P. Tremblin, D. S. Amundsen, G. Chabrier +5

The admitted, conventional scenario to explain the complex spectral evolution of brown dwarfs (BD) since their first detections twenty years ago, has always been the key role playe…
