Astrometric Accelerations as Dynamical Beacons: Discovery and Characterization of HIP 21152 B, the First T-Dwarf Companion in the Hyades
Kyle Franson, Brendan P. Bowler, Mariangela Bonavita +28
Benchmark brown dwarf companions with well-determined ages and model-independent masses are powerful tools to test substellar evolutionary models and probe the formation of giant p…
Updated orbital monitoring and dynamical masses for nearby M-dwarf binaries
Per Calissendorff, Markus Janson, Laetitia Rodet +26
Young M-type binaries are particularly useful for precise isochronal dating by taking advantage of their extended pre-main sequence evolution. Orbital monitoring of these low-mass…
An optimised survey strategy for the ERIS/NIX imager: searching for young giant exoplanets and very low mass brown dwarfs using the K-peak custom photometric filter
Sophie Dubber, Beth Biller, Mariangela Bonavita +5
We present optimal survey strategies for the upcoming NIX imager, part of the ERIS instrument to be installed on the Very Large Telescope (VLT). We will use a custom 2.2 micron K-p…
Constraining masses and separations of unseen companions to five accelerating nearby stars
D. Mesa, M. Bonavita, S. Benatti +39
Aims. This work aims at constraining the masses and separations of potential substellar companions to five accelerating stars (HIP 1481, HIP 88399, HIP 96334, HIP 30314 and HIP 116…
Results from The COPAINS Pilot Survey: four new brown dwarfs and a high companion detection rate for accelerating stars
M. Bonavita, C. Fontanive, R. Gratton +6
The last decade of direct imaging (DI) searches for sub-stellar companions has uncovered a widely diverse sample that challenges the current formation models, while highlighting th…
Binary companions triggering fragmentation in self-gravitating discs
James Cadman, Cassandra Hall, Clémence Fontanive +1
Observations of systems hosting close in ( AU) giant planets and brown dwarfs ( M) find an excess of binary star companions, indicating that stellar mult…
