Characterization of debris disks observed with SPHERE

N. Engler, J. Milli, N. Pawellek +33

This study aims to characterize debris disks observed with SPHERE across multiple programs, with the goal of identifying systematic trends in disk morphology, dust mass, and grain…

Large-amplitude Variability Driven by Giant Dust Storms on a Planetary-mass Companion

Xianyu Tan, Xi Zhang, Mark S. Marley +17

Large-amplitude variations are commonly observed in the atmospheres of directly imaged exoplanets and brown dwarfs. VHS 1256B, the most variable known planet-mass object, exhibits…

Exomoon search with VLTI/GRAVITY around the substellar companion HD 206893 B

Q. Kral, J. Wang, J. Kammerer +130

Direct astrometric detection of exomoons remains unexplored. This study presents the first application of high-precision astrometry to search for exomoons around substellar compani…

High CO/H2 ratios supports an exocometary origin for a CO-rich debris disk

Kevin D. Smith, Luca Matrà, Ke Zhang +9

Over 20 exocometary belts host detectable circumstellar gas, mostly in the form of CO. Two competing theories for its origin have emerged, positing the gas to be primordial or seco…

Horizontal and vertical exoplanet thermal structure from a JWST spectroscopic eclipse map

Ryan C. Challener, Megan Weiner Mansfield, Patricio E. Cubillos +33

Highly-irradiated giant exoplanets known as "ultra-hot Jupiters" are anticipated to exhibit large variations of atmospheric temperature and chemistry as a function of longitude, la…

Compositional characterisation of asteroid (84) Klio with JWST

Tania Le Pivert-Jolivet, Julia de León, Javier Licandro +8

The analysis of the composition of primitive Ccomplex asteroids is essential to understand the distribution of volatiles in the Solar System since its formation. Primitive low-a…
