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…
High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
Combining Gaia and GRAVITY: Characterising five new Directly Detected Substellar Companions
T. O. Winterhalder, S. Lacour, A. Mérand +96
Precise mass constraints are vital for the characterisation of brown dwarfs and exoplanets. Here we present how the combination of data obtained by Gaia and GRAVITY can help enlarg…
Cataclysmic Variables and the disc instability model in the Gaia DR3 colour-magnitude diagram
Guillaume Dubus, Carine Babusiaux
Cataclysmic Variables (CVs) are semi-detached binaries composed of a white dwarf orbiting a lower-mass K or M star. We investigate whether CVs are responsible for a new intriguing…
