Mass-Metallicity Trends in Transiting Exoplanets from Atmospheric Abundances of HO, Na, and K
Luis Welbanks, Nikku Madhusudhan, Nicole F. Allard +3
Atmospheric compositions can provide powerful diagnostics of formation and migration histories of planetary systems. We investigate constraints on atmospheric abundances of HO,…
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…
Debris Disks in Multi-Planet Systems: Are Our Inferences Compromised by Unseen Planets?
Jiayin Dong, Rebekah I. Dawson, Andrew Shannon +1
Resolved debris disk features (e.g., warps, offsets, edges and gaps, azimuthal asymmetries, radially thickened rings, scale heights) contain valuable information about the underlyi…
A dusty benchmark brown dwarf near the ice line of HD 72946

Context. HD72946 is a bright and nearby solar-type star hosting a low-mass companion at long period (P~16 yr) detected with the radial velocities (RV) method. The companion has a m…
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…
TOI-132 b: A short-period planet in the Neptune desert transiting a G-type star
Matías R. Díaz, James S. Jenkins, Davide Gandolfi +45
The Neptune desert is a feature seen in the radius-mass-period plane, whereby a notable dearth of short period, Neptune-like planets is found. Here we report the {\it TESS} discove…
Idealised simulations of the deep atmosphere of hot jupiters: Deep, hot, adiabats as a robust solution to the radius inflation problem
F. Sainsbury-Martinez, P. Wang, S. Fromang +10
Context: The anomalously large radii of hot Jupiters has long been a mystery. However, by combining both theoretical arguments and 2D models, a recent study has suggested that the…
Circumbinary exoplanets and brown dwarfs with the Laser Interferometer Space Antenna
Camilla Danielski, Valeriya Korol, Nicola Tamanini +1
We explore the prospects for the detection of giant circumbinary exoplanets and brown dwarfs (BDs) orbiting Galactic double white dwarfs binaries (DWDs) with the Laser Interferomet…
Debris disks around stars in the NIKA2 era
J. -F. Lestrade, J. -C. Augereau, M. Booth +42
The new NIKA2 camera at the IRAM 30m radiotelescope was used to observe three known debris disks in order to constrain the SED of their dust emission in the millimeter wavelength d…
Probing the subsurface of the two faces of Iapetus
Léa E. Bonnefoy, Jean-François Lestrade, Emmanuel Lellouch +4
Saturn's moon Iapetus, which is in synchronous rotation, is covered by an optically dark material mainly on its leading side, while its trailing side is significantly brighter. Bec…
HD 117214 debris disk: scattered-light images and constraints on the presence of planets
N. Engler, C. Lazzoni, R. Gratton +34
We performed observations of the Sco-Cen F star HD 117214 aiming at a search for planetary companions and the characterization of the debris disk structure. HD 117214 was observed…
Kojima-1Lb Is a Mildly Cold Neptune around the Brightest Microlensing Host Star
A. Fukui, D. Suzuki, N. Koshimoto +56
We report the analysis of additional multiband photometry and spectroscopy and new adaptive optics (AO) imaging of the nearby planetary microlensing event TCP J05074264+2447555 (Ko…
From the stellar properties of HD219134 to the internal compositions of its transiting exoplanets
Roxanne Ligi, Caroline Dorn, Aurélien Crida +8
The harvest of exoplanet discoveries has opened the area of exoplanet characterisation. But this cannot be achieved without a careful analysis of the host star parameters. The syst…

Christophe Mathé, Sandrine Vinatier, Bruno Bézard +6
The Cassini/Composite InfraRed Spectrometer (CIRS) instrument has been observing the middle atmosphere of Titan over almost half a Saturnian year. We used the CIRS dataset processe…
