Warm terrestrial planet with half the mass of Venus transiting a nearby star
Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42
The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…
The SOPHIE search for northern extrasolar planets. XVIII: Six new cold Jupiters, including one of the most eccentric exoplanet orbits
O. D. S. Demangeon, S. Dalal, G. Hébrard +28
Context. Due to their low transit probability, the long-period planets are, as a population, only partially probed by transit surveys. Radial velocity surveys thus have a key role…
Transit detection of the long-period volatile-rich super-Earth Lupi d with
Laetitia Delrez, David Ehrenreich, Yann Alibert +75
Exoplanets transiting bright nearby stars are key objects for advancing our knowledge of planetary formation and evolution. The wealth of photons from the host star gives detailed…
The SOPHIE search for northern extrasolar planets -- XVII. A wealth of new objects: Six cool Jupiters, three brown dwarfs, and 16 low-mass binary stars
S. Dalal, F. Kiefer, G. Hébrard +30
Distinguishing classes within substellar objects and understanding their formation and evolution need larger samples of substellar companions such as exoplanets, brown dwarfs, and…
Six transiting planets and a chain of Laplace resonances in TOI-178
A. Leleu, Y. Alibert, N. C. Hara +152
Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the…
Efficient modeling of correlated noise II. A flexible noise model with fast and scalable methods
J. -B. Delisle, N. Hara, D. Ségransan
Correlated noise affects most astronomical datasets and to neglect accounting for it can lead to spurious signal detections, especially in low signal-to-noise conditions, which is…
