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…
Stellar halo subtraction alternative for accreting companions' characterization with integral field spectroscopy: Analytical and on-sky demonstration on the PDS70, HTLup, and YSES1 systems
R. Julo, M. Bonnefoy, F. Chatelain +5
Context. Medium-resolution IFS, such as MUSE at the VLT, are equipped to detect the emission lines of faint accreting companions when associated with dedicated stellar halo subtrac…
The ExoGRAVITY survey: A K-band spectral library of giant exoplanet and brown dwarf companions
J. Kammerer, T. O. Winterhalder, S. Lacour +106
Direct observations of exoplanet and brown dwarf companions with near-infrared interferometry, first enabled by the dual-field mode of VLTI/GRAVITY, provide unique measurements of…
Constraints on the Orbit of the Young Substellar Companion GQ Lup B from High-Resolution Spectroscopy and VLTI/GRAVITY Astrometry
Vidya Venkatesan, S. Blunt, J. J. Wang +99
Understanding the orbits of giant planets is critical for testing planet formation models, particularly at wide separations greater than 10 au where traditional core accretion beco…
Characterizing the Time Variability of 2M1207 A+b with JWST NIRSpec/PRISM
Arthur D. Adams, Yifan Zhou, Gabriel Dominique-Marleau +13
We present JWST NIRSpec/PRISM IFU time-resolved observations of 2M1207 A and b (TWA 27), a Myr binary system consisting of a K sub-stellar primary hosting a $…
Multi-modal atmospheric characterization of Pictoris b: Adding high-resolution continuum spectra from GRAVITY
M. Ravet, M. Bonnefoy, G. Chauvin +24
We present the first VLTI/GRAVITY observations at R of Pic b. These four high S/N (20) K-band spectra conserve both the pseudo-continuum and molecular absorp…
The mid-infrared spectrum of Pictoris b. First VLTI/MATISSE interferometric observations of an exoplanet
M. Houllé, F. Millour, P. Berio +46
Few spectra of directly-imaged exoplanets have been obtained in the mid-infrared (> 3 m). This region is particularly rich in molecular spectral signatures, whose measurements c…
Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system
Kielan K. W. Hoch, Melanie Rowland, Simon Petrus +26
Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, w…
X-SHYNE: X-Shooter spectra of young exoplanet analogs II. Presentation and analysis of the full library
Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +29
The X-SHYNE library is a homogeneous sample of 43 medium-resolution (R=8000) infrared (0.3-2.5um) spectra of young (<500Myr), low-mass (<20Mjup), and cold (Teff=600-2000K) isolated…
Direct imaging discovery of a young giant planet orbiting on Solar System scales
T. Stolker, M. Samland, L. B. F. M. Waters +102
HD 135344 AB is a young visual binary system that is best known for the protoplanetary disk around the secondary star. The circumstellar environment of the A0-type primary star, on…
The planetary-mass-limit VLT/SINFONI library: Spectral extraction and atmospheric characterization via forward modeling
P. Palma-Bifani, M. Bonnefoy, G. Chauvin +9
We aim to deepen our understanding of the M-L transition on planetary-mass companions and isolated brown dwarfs, and search for evidence of possible differences between these two p…
Orbit and atmosphere of HIP 99770 b through the eyes of VLTI/GRAVITY
T. O. Winterhalder, J. Kammerer, S. Lacour +92
Context: Inferring the likely formation channel of giant exoplanets and brown dwarf companions from orbital and atmospheric observables remains a formidable challenge. Further and…
Differentiating Formation Models with New Dynamical Masses for the PDS 70 Protoplanets
David Trevascus, Sarah Blunt, Valentin Christiaens +22
Hot- and cold-start planet formation models predict differing luminosities for the young, bright planets that direct imaging surveys are most sensitive to. However, precise mass es…
Dust populations from 30 to 1000 au in the debris disk of HD 120326
C. Desgrange, J. Milli, G. Chauvin +15
Context. To date, more than a hundred debris disks have been spatially resolved. Among them, the young system HD 120326 stands out, displaying different disk substructures on both…
