Exoplanets in reflected starlight with dual-field interferometry and a fifth Unit Telescope at VLTI
Óscar Carrión-González, Sylvestre Lacour, Mathias Nowak
In this white paper, we propose an upgrade to the Very Large Telescope Interferometer (VLTI) consisting of the addition of a new 8m Unit Telescope (UT5). The primary goal of this u…
Hunting exomoons with a kilometric baseline interferometer
Thomas O. Winterhalder, Antoine Mérand, Sylvestre Lacour +3
Despite numerous search campaigns based on a diverse set of observational techniques, exomoons - prospective satellites of extrasolar planets - remain an elusive and hard-to-pin-do…
New Orbital Constraints for YSES 1 b and HR 2562 B from High-Precision Astrometry and Planetary Radial Velocities
Jonathan Roberts, William Thompson, Jason J. Wang +20
We present new VLTI/GRAVITY astrometry and updated orbit fits for the directly imaged companions YSES 1 b and HR 2562 B, substellar objects straddling the planet-brown dwarf bounda…
YSES 2b is a background star: Differential astrometric M-dwarf measurements in time
Matthew Kenworthy, Tomas Stolker, Jens Kammerer +13
We wish to confirm the nature of YSES 2b, a purportedly faint companion of the young star YSES 2. We used on-sky observations from SPHERE and GRAVITY to measure the astrometric pos…
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…
VLTI/GRAVITY upper limit on near-infrared emission from the nearby 33 Msun black hole Gaia BH3
Pierre Kervella, Pasquale Panuzzo, Alexandre Gallenne +11
The recent astrometric discovery of the nearby (590 pc) massive () dormant black hole candidate Gaia BH3 offers the possibility to angularly resolve the black hole from…
