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…
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…
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…
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…
