Decoding the radial velocity variations of HD41248 with ESPRESSO
J. P. Faria, V. Adibekyan, E. M. Amazo-Gómez +13
Twenty-four years after the discoveries of the first exoplanets, the radial-velocity (RV) method is still one of the most productive techniques to detect and confirm exoplanets. Bu…
An extremely low-density and temperate giant exoplanet
A. Santerne, L. Malavolta, M. R. Kosiarek +68
Transiting extrasolar planets are key objects in the study of the formation, migration, and evolution of planetary systems. In particular, the exploration of the atmospheres of gia…
The SOPHIE search for northern extrasolar planets. XVI. HD 158259: A compact planetary system in a near-3:2 mean motion resonance chain
N. C. Hara, F. Bouchy, M. Stalport +32
Since 2011, the SOPHIE spectrograph has been used to search for Neptunes and super-Earths in the Northern Hemisphere. As part of this observational program, 290 radial velocity mea…
Exoplanet characterisation in the longest known resonant chain: the K2-138 system seen by HARPS
T. A. Lopez, S. C. C. Barros, A. Santerne +36
The detection of low-mass transiting exoplanets in multiple systems brings new constraints to planetary formation and evolution processes and challenges the current planet formatio…
Expected performances of the Characterising Exoplanet Satellite (CHEOPS) III. Data reduction pipeline: architecture and simulated performances
S. Hoyer, P. Guterman, O. Demangeon +5
The CHaracterizing ExOPlanet Satellite (CHEOPS), to be launched in December 2019, will detect and characterize small size exoplanets via ultra high precision photometry during tran…
The detection and characterisation of 54 massive companions with the SOPHIE spectrograph -- 7 new brown dwarfs and constraints on the BD desert
F. Kiefer, G. Hébrard, J. Sahlmann +35
Brown-dwarfs are substellar objects with masses intermediate between planets and stars within about 13-80Mjup. While isolated BDs are most likely produced by gravitational collapse…
The SOPHIE search for northern extrasolar planets. XIV. A temperate ( K) super-earth around the nearby star Gliese 411
R. F. Díaz, X. Delfosse, M. J. Hobson +33
Periodic radial velocity variations in the nearby M-dwarf star Gl411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to distinguish b…
The Metallicity-Period-Mass Diagram of low-mass exoplanets
S. G. Sousa, V. Adibekyan, N. C. Santos +14
The number of exoplanet detections continues to grow following the development of better instruments and missions. Key steps for the understanding of these worlds comes from their…
HD 213885b: A transiting 1-day-period super-Earth with an Earth-like composition around a bright () star unveiled by TESS
Néstor Espinoza, Rafael Brahm, Thomas Henning +60
We report the discovery of the 1.008-day, ultra-short period (USP) super-Earth HD 213885b (TOI-141b) orbiting the bright () star HD 213885 (TOI-141, TIC 403224672), detected…
