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.…
Astrometric planet search around M8--L2 dwarfs from the ground and with Gaia
J. Sahlmann, P. F. Lazorenko, D. Segransan +4
Ultra-cool dwarfs are very low-mass stars or brown dwarfs and because of their faintness they are difficult targets for radial velocity and transit planet searches. High-precision…
Astrometric search for a planet around VB 10
P. F. Lazorenko, J. Sahlmann, D. Segransan +9
We observed VB 10 in August and September 2009 using the FORS2 camera of the VLT with the aim of measuring its astrometric motion and of probing the presence of the announced plane…
