The Detectability and Constraints of Biosignature Gases in the Near & Mid-Infrared from Transit Transmission Spectroscopy

Luke Tremblay, Michael R Line, Kevin B Stevenson +4

The James Webb Space Telescope (JWST) is expected to revolutionize our understanding of Jovian worlds over the coming decade. However, as we push towards characterizing cooler, sma…

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…

XO-7 b: A transiting hot Jupiter with a massive companion on a wide orbit

Nicolas Crouzet, Brian F. Healy, Guillaume Hébrard +16

Transiting planets orbiting bright stars are the most favorable targets for follow-up and characterization. We report the discovery of the transiting hot Jupiter XO-7 b and of a se…

Distribution and Energy Balance of Pluto's Nitrogen Ice, as seen by New Horizons in 2015

Briley Lewis, John Stansberry, Bryan Holler +10

Pluto's surface is geologically complex because of volatile ices that are mobile on seasonal and longer time scales. Here we analyzed New Horizons LEISA spectral data to globally m…

NaCo polarimetric observations of Sz 91 transitional disk: a remarkable case of dust filtering

Karina Maucó, Johan Olofsson, Hector Canovas +10

We present polarized light observations of the transitional disk around Sz 91 acquired with VLT/NaCo at (1.7m) and (2.2m) bands. We resolve the disk and detect pola…

RefPlanets: Search for reflected light from extra-solar planets with SPHERE/ZIMPOL

S. Hunziker, H. M. Schmid, D. Mouillet +55

RefPlanets is a guaranteed time observation (GTO) programme that uses the Zurich IMaging POLarimeter (ZIMPOL) of SPHERE/VLT for a blind search for exoplanets in wavelengths from 60…
