Astrometric planet search around southern ultracool dwarfs: V. Discovery of the exoplanet candidate PALTA-1 b
J. Sahlmann, P. F. Lazorenko, E. L. Martín +3
We report the discovery of PALTA-1 b, a sub-Jupiter mass exoplanet candidate orbiting the nearby early-L dwarf DENIS-P J1253108-570924 (DE1253-57) located at a distance of ~17 pc.…
Predicting Gaia astrometry's ability to constrain the populations of circumbinary planets
Thomas A. Baycroft, Amaury H. M. J Triaud, Johannes Sahlmann
The coming data releases of Gaia are expected to result in an upheaval of exoplanet science, in particular for long period giant planets (…
ExoDNN: Boosting exoplanet detection with artificial intelligence. Application to Gaia Data Release 3
A. Abreu, J. Lillo-Box, A. M. Perez-Garcia +3
We combine Gaia Data Release 3 and artificial intelligence to enhance the current statistics of substellar companions, particularly within regions of the orbital period vs. mass pa…
JWST 1.5 μm and 4.8 μm Photometry of Y Dwarfs
Loïc Albert, Sandy K. Leggett, Per Calissendorff +20
Brown dwarfs lack nuclear fusion and cool with time; the coldest known have an effective temperature below 500 K, and are known as Y dwarfs. We present a James Webb Space Telescope…
Differential image motion in astrometric observations with very large seeing-limited telescopes
P. F. Lazorenko, J. Sahlmann, M. Mayor +1
We investigate how to quantitatively model the observed differential image motion (DIM) in relative astrometric observations. As a test bed we used differential astrometric observa…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
